It takes a single parameter, which is the date and time value to convert. The TimeZone.ToLocalTime method behaves identically to the DateTime.ToLocalTime method. DateTime.KindĪssumes that the DateTime value is UTC and converts the UTC to local time.Ĭonverts the DateTime value to local time. The exact behavior of the method depends on the value of the object's Kind property, as the following table shows. To convert UTC to local time, call the ToLocalTime method of the DateTime object whose time you want to convert. IIf(cstZone.IsDaylightSavingTime(cstTime), _ĬstZone.DaylightName, cstZone.StandardName))Ĭonsole.WriteLine("The registry does not define the Central Standard Time zone.")Ĭonsole.WriteLine("Registry data on the Central Standard Time zone has been corrupted.") DateTime dateNow = DateTime.Now Ĭonsole.WriteLine("The date and time are.
The following code converts the current local time to UTC and displays the result to the console. The Northern Territory, a town called Broken Hill in New. There are some areas of Australia that observe a non-standard time zone. During Daylight Saving, the area switches to an offset of UTC - 2:30.
Returns the dateTime parameter unchanged. Newfoundland in Canada uses Newfoundland Standard Time (NST) which has an offset of UTC - 3:30. DateTime.KindĪssumes the dateTime parameter is local time and converts local time to UTC. and Canada by the railroads on 18 November 1883. The exact conversion performed by the method depends on the value of the dateTime parameter's Kind property, as the following table shows. Standard Time in the US Standard time in time zones was instituted in the U.S. The easiest way to convert a time to UTC is to call the static ( Shared in Visual Basic) TimeZoneInfo.ConvertTimeToUtc(DateTime) method. Because DateTimeOffset objects store a date and time value along with its offset from UTC, they always represent a particular point in time in relationship to UTC. You can also serialize a DateTimeOffset structure to unambiguously represent a single point in time. NET Framework.) Converting individual time zones to UTC makes time comparisons easy. (For details and other best practices using dates and times, see Coding best practices using DateTime in the. The use of UTC time is recommended when a date and time's portability across computers is important.
Thus, UTC provides a kind of time-zone free or time-zone neutral time. The world's time zones are expressed as positive or negative offsets from UTC. Converting to Coordinated Universal TimeĬoordinated Universal Time (UTC) is a high-precision, atomic time standard.
This topic explains how to convert times from one time zone to another, as well as how to convert DateTimeOffset values that have limited time zone awareness. For example, a Web page that displays the current time in the eastern part of the United States will lack credibility to a customer in eastern Asia. Finally, the railway managers agreed to use four time zones for the continental United States: Eastern, Central, Mountain, and Pacific. An application can no longer assume that all times can be expressed in the local time, which is the time available from the DateTime structure.

The following table maps the time zones that are available on your Windows operating system (which you can select on the Meridium APM Application Server) to their standard time zone names and the abbreviations that will be displayed on the AMS Analytics - Active Alerts and AMS Analytics - Events pages. On these pages, the abbreviated time zone is displayed. The Eastern Standard Time is consistent with UTC -5. Phoenix, for example, is on the 122nd degree of longitude west and thus in the UTC-7 time zone. When you access the following pages, the current time zone of the Meridium APM Application Server to which you are currently connected will be displayed in the Date/Time column. The differences of the several time zones to each other are always specified in relation to the 'Universal Time Coordinated' (UTC), the time on the prime meridian (zero longitude).
