Today I made a point of properly setting the time (it was 14:11 CET), using hwclock to store it and then to retrieve it and everything seemed fine. Then i turned the unit off and started it half an hour later on my ride to school.
The time i set was right there. But it didn't advance. It showed something like 14:20 (time when i turned the TB off), but it was already 14:55.
Then it dawned on me: the time stops when the device is off.
That is ... somewhat scary.
anybody else experienced this? is this a property of the board, fault of my unit, fatal design flaw, an overlook that can be easily fixed by flipping a register in software? evil magic by alien overlords?
(and don't point me to ntp. i know what ntp is and what's it good for, i also know that it won't keep my darned clock in sync unless i go online every time i turn the tb on (which i don't plan on doing))
