Have sw push date/time up to FW

[chrocket]

It would be nice if the SW would push the date/time up to the MCU, so that the files on the SD card could be the real date, and not Jan 1, 1970.

This is probably a lot of work, though.

Hmm, it wouldn't actually be all that much work except that the board isn't always linked to a computer when it is powered on. The file is created when it is powered on, and I'm not sure if there is a way to go back and update the creation time. Worth looking into.
