Unit of measure of time fields on DB[SOLVED]

[dxor]

Hello,
I'd like to understand which is the unit of measure of the fields that describes timing for tickets on database.
For example on the ticket table there are escalation_start_time, escalation_solution_time,...
My target is querying my database to publish on a report which are the timings to resolve requests group by client, category,...
Thanks in advance,bye

As per my knowledge that's in minutes. That's why there is a conversion in brackets, 1440 minutes = 24 hour.

Thank you for your answer, but there's something that I don't understand.
For example I've a ticket that has:
- create_time:2011-01-28 09:50:05, creation_,Escalation_start_time=1296206104, escalation_solution_time=1296204873.
- From the history of the ticket I see that the ticket has been closed in 12 minutes and 44 seconds.

With the unit of measure in minutes,a s you said, the solution time is not right.

That's why there is a conversion in brackets, 1440 minutes = 24 hour.

Sorry but I can't see the conversion hint.
