Scheduled Maintenance Window

As an aside here, I just updated the "iRule Maintenance Windows" tech tip to fix the octal number issue. I did so by removing the math and using string concatenation.

As for your iRule, that looks great. If you want to support 08 or 09 in the morning, you can do so by appending a period after the value

So, this theoretically should work:

if { ([lindex $l 0] eq "Saturday") && 
   ([lindex $l 1] >= 08.) && 
   ([lindex $l 1] < 09.) } { 
   ....

I'm not sure if this is the "best" way to do it, but it does seem to work.

Another option would be to use the "format" command on the lindex command values to convert the values to a number with "g". If you go that route, you'll want to remove the leading zero from your comparison

if { ([lindex $l 0] eq "Saturday") && 
   ([format "%g" [lindex $l 1]] >= 😎 && 
   ([format "%g" [lindex $l 1]] < 9) } { 
   ....

Lots of ways to go about it. Glad to see it's working for you though!
