Use ActiveSupport::Duration to apply time offsets

Using seconds to apply the time offsets when the parsed time is in the past is not time zone aware. This causes issues when DST begins/ends between the two times. For example, daily jobs are scheduled an hour earlier than the are supposed to when DST ends since it doesn't take the extra hour into account. This causes further issues when calculating the next offset time, the offset to prevent scheduling past times doesn't apply as expected and the job is scheduled over and over. As a related issue, we sometimes need a two hour jump to bring the parsed time to the future, add a while loop to handle this case.

Add ability to set a job time zone and also allow running a job at a specific minute of each hour.
