Just calling "gettimeofday()" to get "fPresentationTime" should be OK.

If you're sure that you're delivering each NAL unit individually (i.e., not ever delivering two or more NAL units concatenated together, whether or not they have 00 00 00 01 headers inbetween), then I don't see what could be wrong.

I suggest using "openRTSP" as your client (give it the "-d <duration>" flag, to record a specific length of time).  You should end up with a file named something like "VIDEO-H264-1".  Rename this file to "test.h264".  See whether or not you can play it using VLC.  If you can't, then email it to us (if it's short) or else put it on a web server and send us the URL - so we can inspect it ourselves.
