What does the "Status Change" option indicate

[hamidx64]

In the Ping Monitor section, after you set an IP address for pinging, there is a label called Status Change in that section, which displays a new timestamp each time. On what basis is this value calculated?

Hi, this should indicate the time when the host becomes unreachable/reachable.

If the host now becomes unreachable after some time, the time is updated... and you know when it was down.
