If your like me, youve had occasions where you can't seem to get a valid NTP address.. (and the ZA100 will attempt and log that it failed)coworker reminded me of the public NTP pool..

NTP Pool
Using ntp.pool.org

On the ZA100
Go to Setup | Tools | click on Set Time
Select the Use a Time Server Box
Click Next>

Enter your usual NTP server ...in the first box
(if you dont know one, just enter pool.ntp.org here)

Then pool.ntp.org (in the second dialog box)
Ideally youd choose one server that you *know* for the first entry and the pool for the second due to the slight delay..

And then select your time zone (or also known as time difference (plus or minus how many hours from GMT)
Click Next>

The ZA100 will try to connect to the server(S)
then click Finish then (see next post)

Refresh the browser window

Now check the lower right of the ZA100 and you should have the current time, if not, just repeat the steps and try a different timezone...

Hope people find this useful.. Might add this to suggestions as an option in the set time configuration menu
