Restrict access to VS by ip & time

I have to restrict access to a VS by IP & time. So during a particular window (time/day) only specific ip ranges should be allowed to access that vs. Can someone please guide how to do that on a LTM....

 : I got the permission to try this i-rule tonight. Just quick question, from where this i-rule will pick the clock/time? Would it pick the time from system clock?

Thanks

clock seconds

Returns the current time as an integer number of seconds.

 

An integer value passed to the clock command that represents an absolute time as a number of seconds from the epoch time of 1 January 1970, 00:00 UTC. Note that the count of seconds does not include any leap seconds; seconds are counted as if each UTC day has exactly 86400 seconds. Tcl responds to leap seconds by speeding or slowing its clock by a tiny fraction for some minutes until it is back in sync with UTC; its data model does not represent minutes that have 59 or 61 seconds.
