.NET TimeZoneInfo wrong about Morocco daylight savings
问题 Disclaimer While this question looked like a potential duplicate, it was resolved by referring to IsAmbiguousTime . This does not solve my problem, as the time where I'm noticing discrepancies is not reported to be ambiguous. The question, then... While timeanddate.com says Morocco observes daylight savings between April 3 and July 31 this year, and the current time as provided by worldtimeserver.com seems to imply that this is the case, the .NET TimeZoneInfo does not report Casablanca time
