With the SNMP service installed I obtained the following result with the Net-SNMP utility "snmpgetnext" for a system that had been booted 2071 seconds ago:snmpgetnext -On -v2c -cpublic localhost hrSystemUptime.1.3.6.1.2.1.25.1.1.0 = Timeticks: (2071328) 5:45:13.28As you can see the reported value is in milliseconds while it should be in centiseconds: the SNMP service should return the value 207132 instead of 2071328.This issue occurs at least on Windows XP and Windows 2003, and has been reported several times in public discussion forums.
