Unlike a PC, the raspberry pi doesn't have a battery-backed
real time clock.  If you configure a kernel without the 'fakertc'
device, it will prompt you to enter the time and date when you
power on.  For me this was too annoying, which is why I made the
fakertc device.  With a network connection, the time should be
corrected by aux/timesync soon after booting.

there are RTC modules for the pi (talk over i2c, based on DS1307
or DS3231). i use them with linux distro's and they seem to work fine.

On one RPi I am using a GPS module. I need to add support for its PPS signal for more accurate time keeping.

Thanks Richard.
Yes, I wondered what is this when compiling 9pi.☺

I made over a LAN to wireless bridge yesterday.
When it'd be arrived, I can try it.

Your 9pi is very nice Plan 9 terminal, indeed.
I'm now considering to make a box by myself.
This is because I don't feel them charm than pi itself, 
which we can get from the market now.  
All them are too plasticy and boxy to me.
If could have a time of course.

Kenji

raspberry pi boxes and discussions about them are as varied and
entertaining as program editors.

oh, editors have a 40 year head start.  rpi can't possibly have reached
that level of tedium yet, can they have?

I think Eternal-September saturation levels may have effected a bit of
a steeper curve on the who-cares charts
