excluding a timespan in the middle of FROM, TO

Hello
I muddle through using Analog (because I am a progamming/coding klutz).

I want to exclude a part of the day from my day calculations (this seems
to be the only way to remove a unidentifiable robot that went through
during the time to be excluded).

I want to exclude from 11:45 to 11:51.

The FROM and TO parameters appear only to allow me to exclude *before*
11:45 and *after* 11:51, whereas I want to exclude *after* 11:45 and
*before* 11:51.

Please would you advise?

Thanks for your time
