request for API calls to return for a study-id the date/time of creation and date/time of last modification.

I can scrape the study page html and found the date/time of creation but I cannot find the date/time of last modification of a study. Also I'd much rather have API calls for this than parsing through html. :-)

The PGN tags UTCDate and UTCTime seem to have the date time of creation.
