Custom DDNS fails to update on reboot

[RomikB]

I use "BIND9 DDNS using nsupdate" from https://github.com/RMerl/asuswrt-merlin/wiki/Custom-DDNS to setup my custom ddns.
Script is working if i click apply from a DDNS page, but not working on reboot because time is not synced before ddns-start script executed.
How can I force execute ddns-start script right after time sync, or sync time before ddns-start?
Please help.

Me router is ASUS RT-N16, Firmware:378.50

Try adding ntpclient at the start of your script, to force an immediate ntp update:

ntpclient -h time.nrc.ca

(use your favorite NTP server there)

Thank you. Correct code is

ntpclient -s -h pool.ntp.org
