SSA ver   SSA uptime shows 188 days  but it also shows ports with a last change of 435 days or  343 days as an example.  I thought the last change date would get reset  to 0 days when the SSA is reset or rebooted.  Therefore you would never see a last change date further out than the uptime date.
thnks in advance

Hello Walt,

Before being crunched into readable form (days, hours etc) sysuptime is held in time a tic counter  - a 32 bit unsigned integer.  Rollover for this value is something like 497 days. A lengthy uptime could result in the scenario you describe.
