"Most Cisco devices" is overstating the case. In fact, most low end
Cisco routers, including 2500 series and 2600 series do *not* have a
battery backup for their clocks, so setting the time and date manually
does not survive a router reload - you would have to reset the clock
after each reload.
Another way to set the local clock on the router is to use NTP to point
to an NTP server that does have a reliable clock. After your router is
reloaded NTP will set the clock correctly for you.
