So for the workday-only case, you could have 3 rules: 1. Whitelist of 9AM to 5PM 2. Blacklist Saturday 3. Blacklist Sunday That wouldn't require the code knowing about the concept of a weekend or require the field to be able to handle different days in a single rule, and it'd be pretty easy to either change the restricted days (i.e. weekends) or change the working hours. -- This is an automated message from the Apache Git Service.
