The router clock always matches the Indonesian time zone, so logs, schedulers, vouchers and customer time limits stay right.

A router without a clock battery (most RouterBOARDs) goes back to 1970 after every power cut, so schedulers and voucher uptime limits go wrong until the clock is set again. The NTP client sets the time from the internet automatically. On v6 domain-name NTP servers go in server-dns-names; on v7 servers= is enough.

• Check it: /system ntp client print must show synchronized (v7) or a last-adjustment value (v6), then /system clock print.
• If it still does not sync, check /ip dns (DNS servers set) and whether the output firewall blocks UDP 123.
• v6 with the separate ntp package uses another menu (primary-ntp/secondary-ntp, IPs only). This script is for v6's built-in SNTP client.

How to use: Copy the script, open Winbox → New Terminal, paste. Or Download .rsc, upload it in Files, then run /import file-name=jam-ntp-indonesia.rsc.
