Timestamp for start of run?

Hello there,

I was wondering if there is a way to get the start of an individual run. The only thing I could find so far is the end time with the “date” measurement. I’d like to figure out the exact moment in time when ttfb_start and ttfb_end happened, opposed to the time relative to the run start.

If there is a way to calculate the run start, that would be helpful too!

Kind regards,
