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

Hi,

I test it with this iRule.

when HTTP_REQUEST {
    log local0. [clock seconds]
}

Current time log:

Oct 14 18:11:10 f5 info tmm[18620]: Rule /Common/test_seconds <HTTP_REQUEST>: 1602688267
Oct 14 18:11:10 f5 info tmm[18620]: Rule /Common/test_seconds <HTTP_REQUEST>: 1602688270
...

after change F5 System Time:

May 11 21:11:18 f5 info tmm2[18620]: Rule /Common/test_seconds <HTTP_REQUEST>: 1526062278
May 11 21:11:18 f5 info tmm2[18620]: Rule /Common/test_seconds <HTTP_REQUEST>: 1526062298
...

iRule uses system time.
