Atom 3.0: Is it possible to determine the seconds of the dive start time?

[ATJ]

I have recently acquired an Atom 3.0 and notice that in both the PC and Mac software for loading dives from the PDC the start and end times of the dives only include hh:mm and not the seconds. For a basic log that is perfectly fine, however, I like to synchronise my camera with the PDC so I can determine the depth that a photo was taken. I currently have this all automated with my previous computer (Citizen Cyber Aqualand NX) so it is very simple. I will automate it with the Atom 3.0, but not being able to get the seconds portion of the dive start time means I can only get accurate to the nearest minute - and the depth can change quite a lot in a minute.

I'm guessing it is probably not available but if it is, one of you good people would know how to get it.
