Try something like the following to convert from a DateTime known to be in UTC to the local timezone.

public static DateTime LocalDateTimeFromUtc(DateTime utcDateTime)
{   
    DateTimeOffset dateTimeOffset = new DateTimeOffset(utcDateTime, new TimeSpan(0, 0, 0));
    DateTimeOffset dateTimeOffsetConvertedToLocal = TimeZoneInfo.ConvertTime(dateTimeOffset, TimeZoneInfo.Local);
    return dateTimeOffsetConvertedToLocal.DateTime;
}

you can use addhours method to solve this promble. for example: utc time :2011-08-24 06:25:37 in china +8 hours so in china, the time is :2011-08-24 15:25:37 = 2011-08-24 06:25:37(date)+8(zone)

The Windows Phone 7 .Net framework does not support the ConvertTimeFromUtc function at this time.

For my application I used the ZoneInfo .Net API classes. These use the publicly available timezone database (tz Database / Olson Database). I needed to adapt the classes to read the timezone DB files from Resource streams since Disk IO isnt available on WP7, but other than that the classes all worked well.
