I suppose that only some Finnish software developer knows for sure, and maybe I'll experiment to determine the answer, but does anyone know if the altimeter logbook minutes are rounded vs truncated?

In other words, if a logbook entry says "0:37" does that mean the time was between 0:36:31 and 0:37:30 or was it instead between 0:37:00 and 0:37:59?

Thanks in advance in case anyone happens to know that answer!

And yes, if enough entertaining replies are posted, then I'll explain why I'm curious...
