The clients clearly see only HALF the lease-time: I have set m0n0 to
14400 (default) and 28800 (max), this is what "ipconfig /all" shows on
the XP machine (same goes for the Linux- and OpenBSD-clients):

It's no big deal, I just enter double the values I actually mean,
thought it was a glitch.

Thanks for the answer and kind regards
