Should be plenty of horsepower.  For years I ran a pool.ntp.org server
using a 60mhz armv4 system with 64MB ram.

You don't need anything special in the way of a clock to run a public
ntp server at stratum 2 or lower and achieve millisecond accuracy (or
sub-millisecond at stratum 1, with a PPS input).  I've never seen a
system whose kernel timekeeping was so bad that ntpd couldn't steer the
clock and provide accurate time.
