This is a known problem, and is tracked in dotnet/corefx#11897. There's no built-in solution yet.

However, my TimeZoneConverter library can be used for this.

TimeZoneInfo tzi = TZConvert.GetTimeZoneInfo("Pacific Standard Time");

It works by first seeing if the time zone is present on the computer. If not, then it converts to the equivalent time zone in IANA format (America/Los_Angeles in this case), and trying to retrieve it with that instead. The opposite case also works, so you can use either format on any OS.
