Rolling ontology build should have a time stamp

[pgaudet]

Hello,

The header of the .obo file of the Rolling ontology build (and maybe other files, I didn't check all) should include not just the date, but also a timestamp, since it's built multiple times a day, we have no way of knowing when was the last successful one.

Thanks, Pascale

@pgaudet I think, for our purposes, this would functionally be resolved by #382

But I thought you wanted to keep multiple time.a day ontology generation, in case anything breaks?

Yes, but these are separate use cases (in my formulation). We could blend them, but I think it may be prudent to keep them separate: QC and consumption.
