Time data conversion

Hello to everybody!

I have a very simple question. Assuming that I have the following data

tn = datestr(t2-t1,'yyyy-mm-dd HH:MM:SS FFF')

tn =

2012-01-25 16:11:10 645

is there in Matlab a routine which automicatically translates into milliseconds? Thank you very much!

Jason.

Your question is not quite clear about what you want. One interpretation would be that you want

(t2 - t1) * (24 * 60 * 60 * 1000)

That is, serial date numbers are in full days, so multiply by 24 * 60 * 60 * 1000 to get the time difference as milliseconds.

Here are two conversions you could do:

datevec('2012-01-25 16:11:10 645','yyyy-mm-dd HH:MM:SS FFF')
datenum('2012-01-25 16:11:10 645','yyyy-mm-dd HH:MM:SS FFF')
