Title: Time sync
Post by: tawalker on December 16, 2003, 10:42:59 am

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:
 www.geocities.co.jp/SiliconValley-Bay/1180/download.html
(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...

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 (http://www.openzaurus.org/official/stable/feed/ntpdate_4.1.1a-2_arm.ipk) 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.

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.

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\'
Password:
18 Dec 14:30:03 ntpdate[1237]: adjust time server 132.163.4.101 offset -0.008508 sec
Write to trigger.
set date/time with ntpdate

$

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.

I found out that ntpdate will accept 2 time server addresses.

#!/bin/sh
echo set date/time with ntpdate
su -c \'/home/root/usr/bin/ntpdate 132.163.4.101 192.43.244.18\'
date
exit 0

Err......does anyone know of a place where I can obtain ntpdate?

I\'ve googled...ALL the mirrors are either 404, host can\'t be resolved, or it\'s been bought by the classic \"vapor-ware\" search engines.

(edit: for the sl-5600, sharp rom)

note you might need to stop and restart atd and do \"hwclock -w\" to set the cmos clock instead of just the system clock.  I think the clock application also does this.
