TimeZoneInfo.ConvertTimeFromUtc Method (DateTime, TimeZoneInfo)


Converts a Coordinated Universal Time (UTC) to the time in a specified time zone.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static DateTime ConvertTimeFromUtc(
	DateTime dateTime,
	TimeZoneInfo destinationTimeZone


Type: System.DateTime

The Coordinated Universal Time (UTC).

Type: System.TimeZoneInfo

The time zone to convert dateTime to.

Return Value

Type: System.DateTime

The date and time in the destination time zone. Its DateTime.Kind property is DateTimeKind.Utc if destinationTimeZone is TimeZoneInfo.Utc; otherwise, its DateTime.Kind property is DateTimeKind.Unspecified.

Exception Condition

The Kind property of dateTime is DateTimeKind.Local.


destinationTimeZone is null.

When performing the conversion, the ConvertTimeFromUtc method applies any adjustment rules in effect in the destinationTimeZone time zone.

The precise behavior of this method depends on the value of the Kind property of the dateTime parameter, as the following table shows.

DateTime.Kind property



Throws an ArgumentException.

DateTimeKind.Unspecified or DateTimeKind.Utc

Converts from Coordinated Universal Time (UTC).

If the conversion of dateTime results in a date and time value that is earlier than DateTime.MinValue or later than DateTime.MaxValue, this method returns DateTime.MinValue or DateTime.MaxValue, respectively.

Notes to Callers:

On Windows XP systems, this method applies only the current adjustment rule to the time zone conversion if destinationTimeZone is TimeZoneInfo.Local. As a result, the method may not accurately convert times for periods before the current adjustment rule came into effect. For more information, see the Notes for Callers section in the Local property.

The following example converts Coordinated Universal Time (UTC) to Central Time.

DateTime timeUtc = DateTime.UtcNow;
   TimeZoneInfo cstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");
   DateTime cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone);
   Console.WriteLine("The date and time are {0} {1}.", 
                     cstZone.IsDaylightSavingTime(cstTime) ?
                             cstZone.DaylightName : cstZone.StandardName);
catch (TimeZoneNotFoundException)
   Console.WriteLine("The registry does not define the Central Standard Time zone.");
catch (InvalidTimeZoneException)
   Console.WriteLine("Registry data on the Central Standard Time zone has been corrupted.");
