TIMESTAMPS how to interpret -- HELP

[mis-cs]

Trying to figure out the parameters of the timestamps that are displayed from the "show mac address-table notification command on a 3560-48 running 12.25. We cant make sense of the timestamp and how it relates to actual time. Thanks in advance. Example below , what is 292791393 ?

taken from "show mac address-table notification "

MAC Changed Message :

Operation: Added Vlan: 149 MAC Addr: 0019.e300.c5cc Dot1dBasePort: 46

History Index 0, Entry Timestamp 292791393, Despatch Timestamp 0

This is the value of sysUpTime on the switch when the entry was recorded. sysUpTime is a 32-bit integer that counts the number of hundredths of a second the device has currently been running. So, after the device had been booted for about 4.8 weeks, that MAC was added.
