Every now and then I need to convert a date from Coordinated Universal Time (UTC) to Eastern Standard Time (EST). I always found myself trying to remember: Where did I use this last?. To avoid asking myself, I have now immortalized it on my blog. The solution leverages TimeZoneInfo.ConvertTimeFromUtc. The following will use C# convert utc to timezone and C# convert datetime to utc. This is of course not limited to EST and can be used to c# datetime utc+8 (e.g. utc to rst).
