AFAIK, gpGlobals->time returns the time in seconds since the server booted on a new map, no kludges...

BTW, for the original question, I found a very sophisticated random number generator on the net ! The problem with rand() is that it can only return 16-bit integers, you can't do real 32-bit number generation using rand() ; however some sound libraries use extremely well shaped random number generators for generating sound noise, they are definitely worth a look.
