hi
my rb1000 doesnt save clock setting. it goes back to previous settings after reboot. what do i do?
none of the routerboard have battery, so they all lose clock after reboot. you have to use NTP to synchronize time from a time server
normis, can you please recomment one?
time.nist.gov for one 
google “list of free ntp servers”
normis, after setting NTP client, do i have to set time manually @ system clock?
You should not need to set the time, only the time-zone-name in “system clock”.
Feature wish! Under NTP server it will only store an IP in the router even if you input a DNS. Wish it could also store a DNS entry. Many NTP servers use round robin for load balancing and prefer you use the DNS over the IP. Also, the IP the DNS points at may one day change.
We use this as a work around for now and run it every 7 days with scheduler:
/system ntp client set primary-ntp=[:resolve 0.us.pool.ntp.org]
/system ntp client set secondary-ntp=[:resolve 1.us.pool.ntp.org]
FYI: time.nist.gov used to be marked as very busy.

You have to use script for such tasks.
here is an example:
