TimeZoneInfo.ConvertTimeFromUtc(DateTime, TimeZoneInfo) TimeZoneInfo.ConvertTimeFromUtc(DateTime, TimeZoneInfo) TimeZoneInfo.ConvertTimeFromUtc(DateTime, TimeZoneInfo) Method

Definition

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

public:
 static DateTime ConvertTimeFromUtc(DateTime dateTime, TimeZoneInfo ^ destinationTimeZone);
public static DateTime ConvertTimeFromUtc (DateTime dateTime, TimeZoneInfo destinationTimeZone);
static member ConvertTimeFromUtc : DateTime * TimeZoneInfo -> DateTime
Parameters
dateTime
DateTime DateTime DateTime

The Coordinated Universal Time (UTC).

destinationTimeZone
TimeZoneInfo TimeZoneInfo TimeZoneInfo

The time zone to convert dateTime to.

Returns

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

Exceptions

Examples

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

DateTime timeUtc = DateTime.UtcNow;
try
{
   TimeZoneInfo cstZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time");
   DateTime cstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone);
   Console.WriteLine("The date and time are {0} {1}.", 
                     cstTime, 
                     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.");
}
Dim timeUtc As Date = Date.UtcNow
Try
   Dim cstZone As TimeZoneInfo = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time")
   Dim cstTime As Date = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, cstZone)
   Console.WriteLine("The date and time are {0} {1}.", _
                     cstTime, _
                     IIf(cstZone.IsDaylightSavingTime(cstTime), _
                         cstZone.DaylightName, cstZone.StandardName))
Catch e As TimeZoneNotFoundException
   Console.WriteLine("The registry does not define the Central Standard Time zone.")
Catch e As InvalidTimeZoneException
   Console.WriteLine("Registry data on the Central Standard Time zone has been corrupted.")
End Try

Remarks

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 Conversion
DateTimeKind.Local 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 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.
