Which value are you uploading? I've seen some bpts uploading value in
microseconds instead of seconds, which broke many scripts down the line due
to timestamp being larger than 9999-31-12 23:59:59.999999, which is not
supported by BigQuery. We've now restricted the value to be between 0 and
+1 day from the time on the server, see
https://chromium-review.googlesource.com/c/582009. If you need to upload
different timestamps for some reason, please let me know.

This seems to be a bug in Telemetry code that constructs time: https://github.com/catapult-project/catapult/blob/f80b3a5f20bec44846b3eee573e4a7f5d96372fd/telemetry/telemetry/internal/results/results_options.py#L203

Also cc'ed Ethan & Ben since benchmark_start_ms is also used in results2 UI.

Thanks. Please re-CC me if needed.
