Remove validation on workday start/end time comparison

A respectful feature suggestion: when setting Work Day Start and Work Day End in the Calendar settings for eM Client, allow the start to be “greater than” the end. For example, setting a work day start of 5PM (yes, post meridiem) and a work day end of 2AM (ante meridiem) should be allowed. The reason: some people, including myself, work nights.

it sounds reasonable in your case. I will add it to our official feature requests list.
