Subject: [PATCH] fix: event with invalid timestamp in trace log (#31349)

When node is started within Electron's environment it doesn't
initialize v8 and time of v8's start is never set. As a result
we log v8's start time as 0 and it breaks timestamps in the
trace log. With this change we log v8's start time only when
it was initialized by node.
