Get "Date of reception by server" of an interview

Hello dear SuSo community,

At my institute, we pay our interviewers based on the date they submit interviews to our server via the tablet. For example, if an interview is conducted in January but only uploaded in March, the interviewer will be paid in March.

However, I’m having trouble finding the date the interview was received by the server, even though I know this information exists.

Does anyone have any suggestions on how to locate this date?

Your help is greatly appreciated!

Cheers,
Noé Barthelemy
