I remember this time when I was kinda fanatic about the time of the
server. While scouring some documents I found out that while Windows gets
its time throughout the session from the hardware clock, Linux does not.
Linux just gets the time from the hardware clock on bootup, then uses
something like a software clock. It then synchronizes the hardware clock
with the system clock on shutdown, and perhaps also every so often. I
can't be sure of the latter, though. Just thought I'd share this, in case
you don't know it yet.
What I normally do to update the time of my server is to use a simple
script that:
1. Connects to the Internet ;
2. Uses ntpdate from the xntp3 package to synchronize the system clock
with a time server, right now I'm using tock.usno.navy.mil, there's also
tick.usno.navy.mil and ntp2.usno.navy.mil, among others ;
3. Uses hwclock to synchronize the hardware clock with the system clock by
running 'hwclock --systohc'.
So far it's been okay, and I checked my server right now and ... time's
right. :)
