I'm losing my time...

Has anyone ever seen a node go back to Jan 1, 1970 without running any
date commands. This value is in protected memory no? I have seen - on a
number of nodes - the time jump back from a current date to 0.

Any thoughts?

Doug,
Have those machines been rebooted? I have a problem with one of the
machines I work with that every time I reboot it gets reset (the batteries
drain quickly in my machine, I have custom hardware that hasn’t been tested
for weird stuff like draining the battery). I’d check that and see if it
keeps coming back.

If you haven’t rebooted, I’d be interested to know what DOES reset the time
on you :slight_smile:

Yes it`s protected, by any root program can set it.

Is it the system clock or the RTC that goes back to 0.

Nope, no rebooting. Part of our boot up is actually a synchronization
with the “server” devices on our LAN. The devices that are “losing their
time” don’t actually have rtc’s in them. No batteies.

Ok, aside from a bug in the OS, its possible that one machines remotely changes the time of another. I dont know of any non-drastic
way to prevent or detect that.

How often does this happen? Can you setup a similar machine but
disconnected from the network to see if the problem comes from outside?

Are you running your own program? Are you sure then don’t set the time?

Is someone/something doing an:
rtc hw
on a cpu with no rtc?
