Do not rely on user's system time for telemetry events (#2597)

Some user's don't have their system clocks configured right and we are
seeing events 10 years into the future. I'm stripping out the code that
adds time via the client and am adding it in on zed.dev. We will lose a
little accuracy, as the time will be when the batch hits the server, but
I think its negligible (currently, batches send up every 30 seconds, at
the max) and worth it to protect our data from user's who wonkily dont
set care about their system time.
