Implementation of Time-based QOS/CAR, using "time-range" command

We would like to configure a Time-based QOS/CAR Policy to allow our ISP Customer to have more Burst BW during Weekends then weekdays. In our setup, we color all Burst traffic of all Customers with precedence 1 and then allocate some amount of BW to this shared Pool for precedence 1. So, using Cisco's Technology of "time-range", we have done following config to achieve the said objective. But we are not able to achieve the automatic activation of weekday CAR despite the fact that weekend acces-list/Car gets automatically get deactivated when week-end is over and weekday access-group i.e. 197 gets activated (gets activated but no match in access-group & CAR, can see using show access-list & sh interface rate-limit | include access-group 199 command)

Would appreciate yr valuable input to achieve the desired task.

Configuration :

Interface HSSI 2/0/0

rate-limit output access-group 199 6000000 32000 32000 conform-action transmit exceed-action drop

rate-limit output access-group 197 5000000 32000 32000 conform-action transmit exceed-action drop

Global Coonfig :

access-list 197 permit ip any any precedence priority time-range WEEKDAYS

access-list 199 permit ip any any precedence priority time-range WEEK-END

time-range WEEK-END

periodic weekend 00:00 to 23:59


time-range WEEKDAYS

periodic weekdays 00:00 to 23:59

Note : Customer's Burst Pkts have already been colored with precedence bit 1 i.e priority in CAR statement which are above of these two CAR statements(these CAR statements come in last).
