End of workday exception fails if default time format changed

[bnbeckwith]

I have a Rails application that redefines the default time format. As a result, the regex check for end-of-day fails. This causes me to lose a second/day. #129 fixes the issue by forcing a standard format onto the date instead of relying on to_s. The regex can then check a consistent string representation.

the new release includes a fix for date format handling around regex. Is this still an issue?
