Wrong date/clock for cached objects in RAMN Cache

Hello, I don't understand why the system clock is correct but cache object have 2h delay. I did the command fate just after I deleted the Cache of the LB therefore the object should be fresh

    Perhaps the time used is UTC and it works out the valid date etc. via the configured timezone? Are you +- 2hrs from UTC?

    OK so that confirms it. The output of the show command is displaying the UTC/GMT time, not the 'local' time. It's an output error that I'm sure you can ignore OR this feature works with UTC only and ignores the timezone in all cases which means it works just fine anyway.

      You could always do a quick test, set the expiry to 1hr then connect and see if you get any cache hits.
