inconsistent business day calculation between sunday afternoon and monday AM

[philrosenstein]

When calculating 0.business_days.from_now on a Sunday, I am given Tuesday. But then if I run 0.business_days.from_now again before the start of business on Monday, I am finally given Monday..

Run on Sunday afternoon:

[1] pry(main)> 1.business_day.from_now
=> Wed, 17 Aug 2016 09:00:00 EDT -04:00
[2] pry(main)> 0.business_day.from_now
=> Tue, 16 Aug 2016 09:00:00 EDT -04:00
[3] pry(main)> 0.business_day.ago
=> Fri, 12 Aug 2016 09:00:00 EDT -04:00
[4] pry(main)> 1.business_day.ago
=> Thu, 11 Aug 2016 09:00:00 EDT -04:00

Run on Monday at 8 am EDT:

[5] pry(main)> 0.business_day.from_now
=> Mon, 15 Aug 2016 09:00:00 EDT -04:00
[6] pry(main)> 1.business_day.from_now
=> Tue, 16 Aug 2016 09:00:00 EDT -04:00

@philrosenstein Have you considered the biz gem? (I'm the maintainer.)

It exhibits behavior that might fit your use case well:

>> SUNDAY_AFTERNOON = Time.utc(2016, 8, 14, 14)
=> 2016-08-14 14:00:00 UTC
>> MONDAY_MORNING = Time.utc(2016, 8, 15, 8)
=> 2016-08-15 08:00:00 UTC

>> 1.business_day.after(SUNDAY_AFTERNOON)
=> 2016-08-15 14:00:00 UTC
>> 0.business_days.after(SUNDAY_AFTERNOON)
=> 2016-08-15 09:00:00 UTC
>> 0.business_days.before(SUNDAY_AFTERNOON)
=> 2016-08-12 17:00:00 UTC
>> 1.business_day.before(SUNDAY_AFTERNOON)
=> 2016-08-12 14:00:00 UTC

>> 0.business_days.after(MONDAY_MORNING)
=> 2016-08-15 09:00:00 UTC
>> 1.business_day.after(MONDAY_MORNING)
=> 2016-08-16 09:00:00 UTC

this seems to be related to #149

I'll get a test case and investigate
