Fix Daylight Savings parsing #396
Conversation
Previously the offset change for Daylight Savings was unnecessarily
added all the time, resulting in this discrepancy when the local time
was set to UTC-7:
```
Time.parse('2020-11-01 00:00:00')
=> 2020-11-01 00:00:00 -0700
Chronic.parse('2020-11-01 00:00:00')
=> 2020-11-01 01:00:00 -0700
```
Each time we add an offset to a base time, we need to check whether this
crosses Daylight Savings boundaries. Only if it does should we adjust
the time by the offset.

@leejarvis Are you still maintaining this gem? If so, would you mind reviewing and pushing out an update? This bug causes a number of issues on gems that depend on it. |

There was a problem hiding this comment.
This tests your PR only when system's timezone is one you have, I have different one so for me this test passes either way even without your PR. Need to write such test that would test your specific case with your timezone.

I'm afraid I no longer have time to maintain Chronic. I'm more than open to adding more contributors if anyone is willing though |
