There are two ways I can think of to get the uptime remotely, though
neither with nmap.

1) via SNMP: the sysUpTime.0 OID is the number of 100ths of a second since
   boot. This has a 497-day limit before the 32-bit counter wraps around,
   but if it's a Windows machine I doubt you'll run into that ;-)

2) I'm sure there's an RPC type query which returns this information, but
   it surely requires a network credential.
