either use an offline solution which reconfigures your router at the
specified interval, or try to use time-based ACL together with MQC, i.e.
something like

class-map ALL-TRAFFIC
 match access-group 150
access-list 150 permit ip any any time-range 9to10
time-range 9to10
 periodic daily 09:00 to 10:00
! too lazy now to come up with the exact TB values, 
! but you'll get the idea
policy-map POLICE-IN
  police cir ..<with burst>.. 
    conform-action transmit
    exceed-action drop
 class class-default
  police cir ..<without burst>..
    conform-action transmit
    exceed-action drop

This might not work on all platforms..
