Is it possible to view the last time a file was modified in Windows command prompt in milliseconds or even in seconds?

Do you really mean DOS, or do you mean via a command prompt or batch file in Windows? – Vicky Feb 27 '13 at 13:26
There is no native Windows command line utility that supports viewing time stamps with a resolution of milliseconds.
Your best option would to either use a 3rd party tool or for a native solution (Vista+), use robocopy (supports seconds):
robocopy /L /TS . ..
Tracking a resolution finer than seconds might be trivial or useless as well depending on the file system being used. See http://msdn.microsoft.com/en-us/library/windows/desktop/ms724290(v=vs.85).aspx and http://jpsoft.com/help/index.htm?timestamps.htm
FAT has a write time resolution of 2 seconds.

1The
robocopy /L /TS . ..command works with files to show the timestamp to the second, but it doesn't work with folders/directories :(. Update, thanks to stackoverflow.com/users/479574/mark:forfiles /c "cmd /c echo @path @fdate @ftime". – Rublacava 2 days ago
The robocopy answer does work, but another nice option that works from the standard Windows console (not DOS per se):
forfiles /c "cmd /c echo @file @ftime"
Another user wrote "There is no native Windows command line utility that supports viewing time stamps with a resolution of milliseconds." That is incorrect. Run either of the two wmic commands on a file in an NTFS filesystem and you will see the timestamp to the accuracy of millionths of a second (microsecond which is shorter/smaller than millisecond):

10 millionths of seconds: See https://superuser.com/questions/937380/get-creation-time-of-file-in-milliseconds which has text generated by a different method - "[File] Birth [time]: 2015-03-29 22:16:50.080654200 +0100". "080654200" shows the amount of nanoseconds (080,654,200) or the amount of tenths of microseconds (0,806,542).
Wikipedia says: NTFS Date resolution = 100 ns - https://en.wikipedia.org/wiki/NTFS
