1
|
Write the text rules for the custom time zone.
|
If you want more information, the syntax to write those rules along with a few examples are found in the module in:
/FLASH0/wwwroot/conf/NTP/instructions.txt
|
|
2
|
Using an FTP client, store your rules in the file:
/FLASH0/wwwroot/conf/NTP/customrules
user ID: ntpupdate
password: ntpupdate
|
Root directory to store 'customrules' is set by the FTP server as
/FLASH0/wwwroot/conf/NTP
|
|
3
|
When the rules are written, choose the drop down menu on the NTP configuration screen, and configure (or reboot) the module by selecting:
Time Zone = Custom
|
The NTP component looks for customrules, calls the tz compiler, and generates a new file called 'tz_custom'. This file is binary file and should not be edited.
If the tz compiler detects a syntax error in customrules, the syntax error is logged in the file:
/FLASH0/wwwroot/conf/NTP/error.log
|
