A day on Firrhna is divided into 32 hours of 50 minutes. Times are notated in hexadecimal regardless of the user's Path. For example, 21:25:14 on the 6th of Aiwhura 3482 would be "102412/20/06>1E/1F/0K".
TODO: go over a few of these month and day names, see if we can't think of anything better. Maybe make a proper list of holidays and such instead of naming them in prose.
