1 % STRFTIME Formats a time expressed as msec since the epoch into a string
2 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
3 %
4 % DESCRIPTION: STRFTIME(MSEC, FRMT, TIMEZONE) Formats the time MSEC, expressed
5 % as milliseconds since the unix epoch, 1970-01-01 00:00:00.000 UTC, into a
6 % string, accordingly to the format descrption FRMT and the timezone TIMEZONE.
7 %
8 % The FRMT format description can be a format number or a free form date format
9 % string, as accepted by the datestr() MATLAB function. The FRMT and TIMEZONE
10 % arguments are optional, if they are not specified or empty, the ones stored in
11 % the toolbox user preferences are used.
12 %
13 % EXAMPLES:
14 %
15 % >> msec = time.now();
16 % >> str = time.strftime(msec);
17 % >> str = time.strftime(msec, 'yyyy-mm-dd HH:MM:SS.FFF z');
18 % >> str = time.strftime(msec, 'yyyy-mm-dd HH:MM:SS.FFF z', 'UTC');
