What format is IP SLA History "SampleT"

[Kris Thompson]

I am trying to use IP SLA on a CiscoIOS 12.4(24)T6 router.

It is configure to log failures only. However, we cannot interpet the output "SampleT". It shows a "SampleT" as in Start Time that is not in a recognized or documented format. 

The documentation states that it is now in "milliseconds", but that does not make sense for an Absolute Time, only for a Duration Time.

http://www.cisco.com/en/US/docs/ios/ipsla/command/reference/sla_04.html#wp1133606

Here is the output:

aus-hym-rtr01#sh ip sla history

        Point by point History

Entry    = Entry number

LifeI    = Life index

BucketI  = Bucket index

SampleI  = Sample index

SampleT  = Sample start time

CompT    = RTT (milliseconds)

Sense    = Response return code

Entry LifeI      BucketI    SampleI    SampleT    CompT      Sense      TargetAddr

How can I convert the "SampleT" aka "Sample Start Time" to a Human Date/Time?

And even more frustrating, why can't I find this documented anywhere?

Thanks,

Kris

The SampleT timestamp is the SysUpTime value at the start of operation iteration. A documenation bug CSCua91554 has been filed to add this to the IP SLA command reference for the 'show ip sla history' command.

Thank you.

I don't get it. My SampleT timestamp shows 5785795840. It's about 6.82 days.

But the device uptime is 9 weeks, 3 days, 23 hours, 20 minutes. So how to translate the timestamp into some meaningful time?
