Time sync Options

[tawalker]

I was wondering what NTP clients exist for the Zaurus - that is, for sync'ing the system clock with an Internet time server. ISTR there's a commercial program on Handango ("Drifter"?), but are there any alternatives (command-line or graphical)?

Many thanks,
Tim

Hint: Googling "Zaurus NTP" turned up several hits.

It looks like there is a copy of ntpdate here, with instructions:

(use Babelfish to translate)

I found a beta copy of qpe-ndate, with source code, here:

I haven't tested these, so use at your own risk...

are there any alternatives (command-line or graphical)?

I run this shell script from an icon. (only good for USA time zones)
Substitute for your location.

Opie's date and time settings application has an option to use NTP; it comes as standard on OZ. I'm pretty sure this is the command line NTP program used by Open Zaurus and that it would probably work on a Sharp ROM but I'm not promising.

It works.

# rdate -p 132.163.4.101

This works if it runs with root privilege. I tried server NIST server 132.163.4.101

The time is wrong with rdate after suspend and resume. I need to set the time in the Date/Time application.

Thanks to doseas for finding an app that works.

ntpdate_ntp-4.1.1b-z-4_arm works and the time holds after suspend/resume. I also installed rdate.

# ntpdate 132.163.4.101
18 Dec 05:05:46 ntpdate[12358]: step time server 132.163.4.101 offset 240253.508038 sec
Write to trigger.

sucess!

Sorry for all the posts.

The correct date holds after reboot. ntpdate must change the hardware clock. You don't need rdate for ntpdate to work. Now I can assign an icon to the ntpdate script.

Thanks for the multitude of suggestions here - I'll give them a try!

Here are two scripts to run ntpdate. Call runntpdate from an icon.

# pwd
/home/QtPalmtop/bin
# cat runntpdate
#!/bin/sh
qcop QPE/Application/embeddedkonsole 'setDocument(QString)' '/home/QtPalmtop/bin/setntpdate.sh'
exit 0
#
# cat setntpdate.sh
#!/bin/sh
su -c '/home/root/usr/bin/ntpdate 132.163.4.101'
echo set date/time with ntpdate
date
exit 0
#

output looks like this in embeddedkonsole.

$ su -c '/home/QtPalmtop/bin/setntpdate.sh'

You can use rdate to set the software clock and sync the hardware clock.

Sending a command to the pipe /var/spool/at/trigger causes the hwclock to sync up with the software clock. That is what ntpdate does.

# rdate 132.163.4.101
# echo 'W' > /var/spool/at/trigger

I verified that the adjusted date and time hold after suspend/resume and after reboot.
