Convert LocalDateTime to/from TM

The MAXON API provides the developer with two practical global functions to convert maxon::LocalDateTime to ANSI tm struct and vice versa.

Provided functions are:

maxon::ConvertLocalDateTimeToTM() : converts maxon::LocalDateTime to ANSI "tm" struct;
maxon::ConvertTMToLocalDateTime() : converts ANSI "tm" struct to maxon::LocalDateTime .

From LocalDateTime to ANSI tm:

// This example converts a LocalDateTime to a tm.

const Int32 year = 2016; const Int32 month = 7; const Int32 day = 1; const Int32 hour = 9; const Int32 minute = 0; const Int32 second = 0; const maxon::LocalDateTime ldt = maxon::LocalDateTime::FromValues (year, month, day, hour, minute, second) iferr_return ; const tm tmvalue = ConvertLocalDateTimeToTM (ldt);

From ANSI tm to maxon::LocalDateTime :

// This example converts a tm object to a LocalDateTime object. tm tmvalue; tmvalue.tm_year = 2016; tmvalue.tm_mon = 7; tmvalue.tm_mday = 1; tmvalue.tm_hour = 9; tmvalue.tm_min = 0; tmvalue.tm_sec = 0; const maxon::LocalDateTime ldt = ConvertTMToLocalDateTime (tmvalue);
