I need to translate those dates and time (strings)

'25-Mar-2014 13:00:00'
'07-Nov-2018 18:30:45'

to the forllowing format (in string as well):

'2014-03-25T13:00:00.000Z'
'2018-11-07T18:30:45.000Z'

Any idea how to handle such kind of formats? I find it pretty complex...

Yes. datestr is a remnant of the deprecated datenum that didn't have a formatting option; it is just a particularly-scaled double.

char(dt) is the idiom if need the character array; for most purposes however, either cellstr or string is probably more useful/less coding downstream--but depends upon just why you actually need the string representation at all...

I need to get a response from a statistical data API on the internet. This API only takes this kind of format. Do you have any suggestion how to get posix time from the format? string: timestr='2014-03-25T13:00:00.000Z'?

EDIT: Okay figured out. First I use t= datetime(timestr,'Format','yyyy-MM-dd''T''HH:mm:ss.SSS''Z')

then just posixtime(t)
