It wouldn't be as ugly as that, you don't need conditionals. Just
${run a program or script that writes the appropriate delay string to
stdout, which is available to you in $value.

I don't know about "better". You good do something a lot uglier
looking but possibly faster within exim by using one of the $tod_*
variables and ${sg or ${substr to get the time/date components you
want (day of week, hour) into $acl_mN variables. Then a long set of
nested ${if to set the desired delay. Hmm, or maybe an lsearch
file...
If it were me, I'd write a small C program (for performance) to
calculate the delay and ${run it.
