I don't know what OS you are using but this is used by Windows Server time services to synchronise networks. It sounds like more work than what you have at the moment, but it would mean that if you move your server again then you don't need to recode the DateTime handling.Īnother point to look at is clock synchronisation between the server and the clients using NTP (Network Time Protocol) or SNTP (Simple Network Time Protocol) if it is accurate enough. If you're including dates as well and need to cope with say US MM/dd/yyyy and european dd/MM/yyyy formats the you can use CultureInfo class to parse the DateTime value accordingly. Z-time (Coordinated Universal Time) All aspects of meteorology are based upon a world-wide 24-hour clock called Zulu time (Z), more commonly called Coordinated Universal Time (UTC). Then you can convert it using DateTime.ToLocalTime or DateTime.ToUniversalTime as requried. You can get time data in UTC format from the server. Convert UTC to EDT time zone, calculate the time difference between Universal Time (UTC/GMT) and Eastern Daylight Time (North America) (EDT). It will also allow you to show the times in any timezone that you wish by use of different Culture objects. GMT +01:00 DST 2:55:02 PM Western European Time GMT +02:00 DST 3:55:02 PM Central European Time GMT +03:00 DST 4:55:02 PM Eastern European Time European. You then convert it to UTC to send back to your server.Įither way your server doesn't need to know where the client is so if you have multiple clients in multiple timezones then all calculations will match. If you're using client-server architecture then if the LocalTime call is on the client side it will display the LocalTime for the client. Look here for a full explanation: Microsoft link on displaying local user time for web pages. HttpRequest.UserLanguages to help create a CultureInfo object and use that to parse your DateTime object. Greenwich Mean Time is 5 hours and 30 minutes behind India Standard Time and 4 hours ahead of Eastern Daylight Time. Im trying to use LastBoot in a query and it displays in UTC, how can I covert to my EDT Do I just do the math and subtract 5 or is there a better SWQL way. Quickly convert Coordinated Universal Time (UTC) to Eastern Daylight Time (EDT) accurately using our converter and conversion table. Territories observing the time zone are primarily in North America a. That means to find the standard time in the zone you must subtract four hours from Coordinated Universal Time. If you're using web pages to access your server then use Eastern Daylight Time is four hours behind the Coordinated Universal Time standard, written as an offset of UTC - 4:00. I would have said that you should use UTC for calculations of time periods, so that you avoid issues of daylight saving time and then use LocalTime for display only.ĭateTime.ToLocalTime for UTC to whatever the local time zone is and then DateTime.ToUniversalTime to convert from local time to UTC.ĭo I take it then that you're after displaying a different timezone to that of the server?
