Clock - UTC - Give The Users Current Time Zone/local Time
Jul 22, 2011
So I currently have the following:
2 timers
2 labels
1st label is "Clock" this pulls the time from the users current time zone/local time
2nd label is "UTCClock" Which would be UTC time
Now I have this for the first label: clock.Text = Format(TimeOfDay, "hh:mm:ss tt")
Which would give the users current time zone/local time. As for the UTC.. how would I add in for the UTC time from where the user is located at? I did some searches.. but couldnt find what I was looking for.. IM pretty sure its not as easy as getting the users current time zone/local time.. So im assuming that Theres a "bit more" code into getting UTC time..

I used .NET Framework 1.1 in C/S project before. Now I have updated the project to use .NET Framework 3.5 without modifying source code, but I have found that : the Remoted DateTime values can not be converted to the equivalent local time of a remote computer that is in a different time zone. In .NET Framework 1.1, the DateTime values can be converted automatically.

I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?

I have a program that reads a file with Pacific Daylight Time, I want users to see the time and date in their local environment.
At present I have in Australia a time difference of 18 hours, so I have a list box with -24 to +24 and currently set at 18, my code is elementary as long as I have moved past day one of the month it suits me personally, but I want to distribute my app, so I need something better.

Basically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.

i am using Visual Studio 2008, .net 3.5sp1 When i do the following oracle query on Oracle9i database
a)select NEW_TIME( sysdate, 'EDT','EST') as NT from dual;it works ok on Sql Developer and from vb.net
b) select NEW_TIME( sysdate, EXTRACT(TIMEZONE_ABBR FROM CURRENT_TIMESTAMP),'EST') as NT from dual;
c) select NEW_TIME( sysdate, to_char(EXTRACT(TIMEZONE_ABBR FROM CURRENT_TIMESTAMP)),'EST') as NT from dual;
Both b) and c) work okay on Oracle Sql Developer but fail when run via vb.net with error: ORA-01857: not a valid time zone
I want either b) or c) to be run successfully from .net I also tried replacing 'sysdate' with 'current_timestamp' and the results are similar.

I'm writing a report scheduler that is somewhat of a clone to the backupexec scheduler and the layout can be seen in post #10 here: [URL]..It works great and saves/edits/deletes records just fine, but now i need to compare those records one at a time in a windows service that i'm writing in order to trigger automated report creation and emailing - i already have the report and i already have the code for the emailing, i'm just looking for the most efficient way to loop through the table (that i've pulled in to a dataset) and compare its records with the current date and time - if true, the event fires.
[Code]...
1stSun, 2ndSun etc are bit fields, time is a datetime, and the remainder are varchar. My service checks the database every thirty seconds.The english version of what i'm trying to do is "Connect to the database, grab the entire table (it will always only have 5-6 entries max, so i felt 30 second sweeps was okay), and If today is the 1st Sunday of the month, and it is currently 11:00:00 a.m. (could be any day or time, this is just an example) - loop through the dataset to identify if any records match the time field or greater - if they do, fire the report

I have a form with the DateTimePicker control on it. When I select a date it gives a value like "date time" (Eg.: 5/12/2010 12:20:35 PM). But here the time returned is current time. What I need is for the date chosen from the picker automatically set the time to 00:00:00 instead of the time when the date was picked.

I'd like to write a small app to get the time from an "atomic" clock -- I believe the UTC time and then compare this against the system clock.
So far I've been able to get the system time details with the code below but just cannot figure out where to start on getting the atomic clock(s) time.
I did Google this for examples and have not found anything useful, I did find a list of atomic time servers @ the following URL and realise I have to connect to NIST Internet Time Service clock
Dim localDirect As Date = Date.Now
Dim utcDirect As Date = Date.UtcNow
Dim localFromUtc As Date = utcDirect.ToLocalTime()

I would like to make an alarm clock application, however I am having some problems in the brainstorming phase.
My main problem is the fact that I dont know how to ensure the application will be able to calculate the time and thus set off the alarm. For example, when the application is closed, how will the alarm go off?
Ideally I would like to make this app a system startup item, so if the system is rebooted, the application will automatically relaunch - but again, I dont know how to do that.
If the system is sleeping, how can I wake it up? These kind of problems.
Another dilema I have, is if this application is always running, how could I have it go to my taskbar hidden icon menu (the right section of the taskbar next to the time).

I need to add a clock to a web page. The clock needs to be synchronized with a server but I really don't want to have it constantly check the server as the page will be open 24/7 on several PCs. Is there some way to get the time from the server and then use the systems clock to keep it updated and check the server every 15 minutes or so to keep it synced?

In my program's Form_Load I randomly generate a time value. Once I generate the time value, I put it in a DateTime variable. I need it to work like a clock. I know I can do this with a timer with an interval of 60000, or using TimeGetTime and updating a variable.Is it possible to do this with a thread?

I have a table which contains the start date and end date, in my db. What I currently do is simply display both the fields in a ListView control. But instead of that approach, I'm thinking about displaying a 'clock' image and shading those areas with some color. This is similar to a Pie Chart. But the only difference is, I'm going to display a clock's image as background and the shading is based on the time.

I'm in need of a "global" type timer that will allow me to basically run a clock the entire time someone is on my site, no matter what pages they go to. I've played around with the timer available for forms but I didn't see a way to make it continue to run after someone left that page.The effect I'm attempting to create is for a timer to start whenever someone hits my site, then every X minutes an event will trigger. This event should happen no matter where they are on the site. I've read a couple articles on timers but to be honest I'm fairly new to VB and I didn't know if I really needed to learn about 'threading' etc, to get a timer to work.
