Issue Summary

Sprint dates in Advanced Roadmaps (AR4J) do not reflect the same date in Agile boards if the sprint start/end time in the user timezone vs UTC don't fall on the same day.

This is reproducible on Data Center: (yes)

Steps to Reproduce

1. Set the user timezone to CET (UTC+1)
2. Create a sprint that starts at 00:59 on a given date D
3. Go to view the sprint in AR4J

Expected Results

The sprint start date should be D

Actual Results

The sprint start date is D-1

Workaround

Make sure the sprint start time is greater than the time offset of the user timezone to UTC.
For instance, if you're in the CET timezone, sprint start times should be after 01:00.

Notes

• The issue occurs despite checking Plan default to system timezone under Plans > Administration > Early Access Features.
• This was supposed to be fixed in JPOSERVER-2281.
