Get UTC Time, Convert a UTC time to Datenum (both Win32/Linux versions)

Get a UTC time using standard C time function, convert UTC time to MATLAB serial date ...

Description

UTC time (universal time convention) is used in ANSI-C standard for defining time. This is measured in seconds since 1970, at the Prime Meridian. By definition, there is no adjustment in this number for Daylight Savings time. the UTC_TIME function uses a C-MEX function to get the System Time in UTC format.

Another function UTC2DATENUM will convert any UTC time to the correct MATLAB serial date number. This is done with the help of the C-function gmtime. Because this function should properly handle daylight savings time adjustments going from UTC to the local time used by the MATLAB serial date number.

This package just brings a Linux compatibility.
