====== Set and fix clock issue ======

===== Set time zone =====

1. Edit **''/etc/timezone''**, for example set to Hong Kong:
<code>
Asia/Hong_Kong
</code>

Or, run:
<code>
dpkg-reconfigure tzdata
</code>

2. Copy the zone files **''/usr/share/zoneinfo/Asia/Hong_Kong''** from the build-box.


===== Fix clock issue =====

If using the kernel 2.6.26-486-voyage, or 2.6.30-voyage (Update: also for 2.6.38-voyage) and a ALIX board, the clock must be fixed.

1. add "clocksource=tsc" to kernel param:
<code>
kernel /vmlinuz root=LABEL=ROOT_FS console=ttyS0,38400n8 clocksource=tsc
</code>

2. sync time automatically with ntp daemon. Install ntp and edit ''/etc/ntp.conf'':
<code>
driftfile /var/tmp/ntp.drift
...
broadcast 192.168.0.255
</code>

3. set time right ASAP, add ''rdate'' command in ''/etc/init.d/ntp'':
<code>
...
case $1 in
        start)

                # use rdate to quickly set clock
                rdate -u -s stdtime.gov.hk
</code>

4. disable the hook scripts that interfere with the startup of ntp daemon:

  * ''/etc/network/if-up.d/ntpdate''
  * ''/etc/dhcp/dhclient-exit-hooks.d/ntpdate''
  * ''/etc/dhcp/dhclient-exit-hooks.d/ntp''

  
===== TO-DO =====
Compile a new kernel so that "clocksource=tsc" is not needed.
