How to set a time zone or a Kind of a DateTime value

Question

I mean to store strict UTC time in a DateTime variable and output it in ISO 8601 format   To do the last I ve used  ToString  yyyy-MM-ddTHH mm sszzz    and it has uncovered that the time zone is UTC 01 00   I ve tried to use  Kind   DateTimeKind Utc  but it says the Kind property has no setter   How do I explicitly specify the time is in UTC  How is the Kind property set

While the DateTime Kind property does not have a setter  the static method DateTime SpecifyKind creates a DateTime instance with a specified value for Kind   Altenatively there are several DateTime constructor overloads that take a DateTimeKind parameter

If you want to get advantage of your local machine timezone you can use myDateTime ToUniversalTime   to get the UTC time from your local time or myDateTime ToLocalTime   to convert the UTC time to the local machine s time      convert UTC time from the database to the machine s time DateTime databaseUtcTime   new DateTime 2011 6 5 10 15 00   var localTime   databaseUtcTime ToLocalTime        convert local time to UTC for database save var databaseUtcTime   localTime ToUniversalTime      If you need to convert time from to other timezones  you may use TimeZoneInfo ConvertTime   or TimeZoneInfo ConvertTimeFromUtc        convert UTC time from the database to japanese time DateTime databaseUtcTime   new DateTime 2011 6 5 10 15 00   var japaneseTimeZone   TimeZoneInfo FindSystemTimeZoneById  Tokyo Standard Time    var japaneseTime   TimeZoneInfo ConvertTimeFromUtc databaseUtcTime  japaneseTimeZone       convert japanese time to UTC for database save var databaseUtcTime   TimeZoneInfo ConvertTimeToUtc japaneseTime  japaneseTimeZone     List of available timezones  TimeZoneInfo class on MSDN
