Converting time from different timezone with daylight savings included

Question

I have process that accepts datetime value with timezone as a string (data comes from outside system). I need to translate this datetime to what the time would have been at the local machines timezone.

Example code:

string cetId = "Central European Standard Time";
if (timeZone == "CET")
{
    TimeZoneInfo cetZone = TimeZoneInfo.FindSystemTimeZoneById(cetId);
    returnDateTime = TimeZoneInfo.ConvertTime(statusDateTime, cetZone, TimeZoneInfo.Local);
}
else if (timeZone == "CEST")
{
    TimeZoneInfo cestZone = TimeZoneInfo.FindSystemTimeZoneById(cetId);
    returnDateTime = TimeZoneInfo.ConvertTime(statusDateTime, cestZone, TimeZoneInfo.Local);
}

Do I need to do anything specific if the time is CEST (central european summer time) instead of CET (central european time) or does .net TimeZoneInfo object handle that scenario?

Answer 1

You should be fine.

You are telling ConvertTime what both time zones (source and target) are.

Do you have a specific problem with this or are you just asking for confirmation?
