What is the time format in Bitbucket API?

I was trying to retrieve a report in a Bitbucket instance. The return from the API contains event dates. However, the value looks strange. It is something like 1680143775227.

The format looks like Unix Epoch Timestamp. But it was converted to a far future time in any online converters.

The .Net action [System.DateTime]::UnixEpoch.AddSeconds() threw an error:

MethodInvocationException: Exception calling "AddSeconds" with "1" argument(s): "Value to add was out of range. (Parameter 'value')"

The solution is using [System.DateTime]::UnixEpoch.AddMilliSeconds() to convert the time.

Such format calls Epoch Milliseconds or Unix Time in Milliseconds.
