    Description

      Since the landing of patch https://review.whamcloud.com/33201 "LU-11407 obdclass: add start time to stats files" the "snapshot_time" in the Lustre stats files has incorrectly been reporting the timestamp relative to the system boot rather than the Unix wallclock time. This should be reporting the wallclock time so that the stats can be correlated across nodes more easily.

      In some cases this may not be noticed, because the monitor is only comparing the relative time interval between samples, and/or records its own timestamp when the stats are collected, but this should be fixed.
