For more information on how GitHub handles the dates specified in DueOn, please refer to this support forum post: https://github.community/t5/How-to-use-Git-and-GitHub/Milestone-quot-Due-On-quot-field-defaults-to-7-00-when-set-by-v3/m-p/6901

Please note that due to artifacts of how GitHub was originally designed, all timestamps in the GitHub database are normalized to Pacific Time. This means that any dates specified that occur before 7am UTC will be considered timestamps for the previous day.

Given that GitHub drops the time aspect of this DateTime, this function will ensure that the requested DueOn date specified is honored by manipulating the time as needed.
