When you’re ready to start data harvesting from your Fetch instrument it is good practice to make a note of the real time from your watch or a clock, but what’s the benefit of this?

By recording the real time from your watch/a clock when you start data harvesting, you can compare it with the reported time given in Subsea Array Manager (SAM), noting the time given in SAM is in UTC/GMT.

This way, if a time error occurs, you can use these time figures to work out what has happened and adjust your harvested data accordingly.
