In the dagit UI I see "Timing" next to runs, is there a context.run_config['timing'] or something like that?

Hi Jayme - this is a bit clunky but I suspect would get the job done:

from dagster import RunsFilter

# Within the op or resource
run_record = context.instance.get_run_records(RunsFilter(run_ids=[context.dagster_run.run_id]))[0]
start_time = run_record.start_time

Woo - wizardry. Thanks @daniel!

its a unix timestamp, so UTC

Got it. Thanks again!
