+ − % STRFTIME Formats a time expressed as msec since the epoch into a string
+ − %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+ − %
+ − % DESCRIPTION: STRFTIME(MSEC, FRMT, TIMEZONE) Formats the time MSEC, expressed
+ − % as milliseconds since the unix epoch, 1970-01-01 00:00:00.000 UTC, into a
+ − % string, accordingly to the format descrption FRMT and the timezone TIMEZONE.
+ − %
+ − % The FRMT format description can be a format number or a free form date format
+ − % string, as accepted by the datestr() MATLAB function. The FRMT and TIMEZONE
+ − % arguments are optional, if they are not specified or empty, the ones stored in
+ − % the toolbox user preferences are used.
+ − %
+ − % EXAMPLES:
+ − %
+ − % >> msec = time.now();
+ − % >> str = time.strftime(msec);
+ − % >> str = time.strftime(msec, 'yyyy-mm-dd HH:MM:SS.FFF z');
+ − % >> str = time.strftime(msec, 'yyyy-mm-dd HH:MM:SS.FFF z', 'UTC');
