Missing export parameters

[Silty Sam ReDo]

A non-profit I dive for - recovering ghost traps off the Maine coast - needs a dive log for their grant money record keeping.

It would be a great help if I could export the time-related data from my computer downloads, either the actual dive duration or values that it can be calculated from.

What is "total duration" that IS an export parameter? I don't recognize that value.

thanks

(Can I add: MacDive is one of the few things in my dive world that works flawlessly. Really enjoy getting my gear off and dumping the data into my phone or whatever is handy.)
