You can use parse-time-string which can handle this.  It returns
a decoded time.

Even more general:
Org-mode has a very general time parsing function, org-read-date.  It
gobbles pretty much anything that looks like a date and/or date.
It normally reads from the user input, but you can also make it
read from a string:

(org-read-date t t "2007-02-03")

This will return an internal emacs time, time-date can take it from
there, for example use time-to-days to get an absolute day number.
