Seconds UTC to Matlab Datenum by Dan

There are a lot of ways to do this on the Internet. This version is 1-line long. (datenum, utc, time)

utc2datenum(sec)

unix time to matlab time converter by Georg D

converts matlab time into unixtime or unixtime into matlab time (unix time, datenum, datevec)

unixtime(inputtime)

DateStr2Num by Jan Simon

Convert date string to date number - CMex: much faster than DATENUM (datevec, date, serial)

DateStr2Num(S, F)

uTest_DateStr2Num(doSpeed)

mdatestr, mdatenum: A simple alternative of datestr and datenum by Zhiqiang Zhang

the original datestr and datenum are powerful, but slow. The two functions' are limited, but faster. (datetime, datenum, datestr)

mdatenum(S)

mdatestr(D)

DateConvert by Jan Simon

Simple but fast date conversion: 1.3% of DATESTR time, 20% of DATEVEC/ DATENUM time (conversion, string, serial date number)

DateConvert(DIn, OutFormat)

TestDateConvert(doSpeed)

Round off dates and times by Kevin J. Delaney

Rounds off a datenum to the nearest second, minute, hour, day, month or year. (datenum, round, date)

tlabel.m v2.6.1 (Sep 2009) by Carlos Adrian Vargas Aguilera

Same as DATETICK but with ZOOM, PAN, LINKAXES and more! (zoom, datetick, xlabel)

tlabel(varargin)

Exact Datevec Second Data by Patrick Flick

This function bypasses the problem with rounded date values, caused by the floating point representa (datenum, rounding, datetime)

resultDateVec=exactDatevecSecondData (datenumValues)

DATEPART by Ian Howat

Extract decimal yr/month/day/hr/min/sec from a datenum. More versatile than datevec. (clock, fun, date)

datepart(din,varargin)

Convert Time Array to a Datenum Array (Win32) by Mark Evans

Converts a (Mx1) arrays of UTC time to a (Mx1) array of MATLAB serial dates (utc, datenum, time)

Get UTC Time, Convert a UTC time to Datenum (supports vectors, Win/Linux) by Abraham Cohn

Get a UTC time using standard C time function, convert UTC time to MATLAB serial date ... (utc, time, datenum)

utc2datenum.m

utc_time.m

Universal Time Code by Anders Björk

Converts UTC from and to MATLAB datenum. (clock, fun, utc)

time_ml_format=utc2date(UTCtime,Timezone);

utc=date2utc(datenumber,Timezone);
