Update: Daylight Savings Time -> Standard Time (N.America)

The change from Daylight Savings to Standard Time in N. America didn't work. I had to manually adjust the time. This should be automatic: it is in Ubuntu and Windows.

 

ubuntu and windows connects to a time server : nist.gov or windows.com

Linpus did not even add this feature, hence, you really have to update time by yourself.

 

Really, mine changed all on its own.

 

Hmm, my palm pilot updates its time without needing an internet connection.

Most modern software changes the time at a specified day of the month, it doesn't have to have an internet connection to maintain the time.

The software just doesn't include an automatic changeover option I guess. It might be hidden.

 

I couldn't find any option for DST on my Linpus machine. Had to change it myself. But that's cool; I drive a stick-shift car, too.......Jake

 

Linpus fully supports timezones. Note that the rules for daylight time etc. change according to which timezone you are in. Also, the rules CHANGE, so converting from Universal Coordinated to local can be tricky (you need the timezone data, including any corrections for the full time covered by any time calculations).

In any case, you will find the rule files in /usr/share/zoneinfo. There are 1674 time zones supported (on my AAO). FYI: to find this out:

$ cd /usr/share/zoneinfo
$ find . -type f | wc -l
1674

The current timezone is in /etc/timezone

$ cat /etc/timezone
America/Toronto

$ sudo mousepad /etc/timezone

to edit this file. Note that if (when) timezone rules change (eg. Bush changed DST rules in the US -- and they changed throughout NAFTA as a result), the timezone file is corrected. Its a standard format.

The date command will also print out what the effective timezone is:

$ date
Wed Nov 12 16:39:49 EST 2008

is my output, showing that the system indeed thinks that EST (Eastern Standard Time, aka America/Toronto) is in effect. I don't have a second AAO (and I am actually using mine, thanks), but I imagine (guess) that the default timezone is "Factory" and that appears to have no corrections at all. The next time I actually reboot, I will try this out...

Another fun command is zdump, which tells you the time in different zones:

$ zdump EST CET UTC
EST Wed Nov 12 16:46:54 2008 EST
CET Wed Nov 12 22:46:54 2008 CET
UTC Wed Nov 12 21:46:54 2008 UTC

 

Have you got the ntp daemon installed and running? To install:

Code:

 sudo yum install ntp

May need to ensure that it runs at boot:

Code:

 sudo /sbin/chkconfig --levels 345 ntpd on

chkconfig (the normal sysv/redhat startup mechanism) is not really supported with the AAO. Reason is (I suspect) to reduce boot-time.

/etc/rc.local can be used, or have a look at /etc/rc.d/slim/wait.sh and /etc/rc.d/slim/nowait.sh. The OS for the AAO seems to have "pulled in" some BSD startup stuff (from Slackware).
