The correct OID for system uptime

I use SNMP to track system uptime so I know when my hosts have recently rebooted, but I keep making a mistake when picking which OID to monitor and using sysUpTime.0 which is wrong I should be using hrSystem.hrSystemUptime.0.

sysUpTime.0

Timeticks (0.01s) since the snmpd started.

hrSystem.hrSystemUptime.0

Timeticks since the hardware started.
