toString(long time)
The current documentation omits some vital information.
The input d_time value is assumed by the function to be a UTC date-time. It is first converted to the local date-time by this function and then converted to a string.
toTimeString
The input to toTimeString() is assumed to be UTC, and it outputs a Local time string. (
NG:digitalmars.D.learn/3229).
Convert long to Date
I didn't see a built-in function to convert long to Date struct. Did I miss anything here?
C# style TimeSpan
It would be sweet to include a C# style TimeSpan class/struct in std library.
/************** C# Example **************/ DateTime date1 = DateTime.Now; DateTime date2 = DateTime.Now; TimeSpan span = date1 - date2; Console.WriteLine(span); /********** End of C# Example ***********/
