Changing the start/end time of a Challenge

Hi, I am trying to create a challenge with a dev and a test phase, and they are automatically created to start/end at 02:00 CEST. This generates a conflict in case I set dev and test phases to start at the same day but at different intervals (i.e., Phase "Test" must start after phase "Development" ends). If I set them two start at two different days, both will start/end at 02:00 CEST, and I may lose some hours. Is there any way to edit the start/end time of a challenge on Codabench? Best

TODO

• Allow phase 1 end and phase 2 start dates to be same (actually it's possible already)
• Fix the interface so we don't need to click again on the dates to hide the error message Solved by: #1163
• Phase start/end time: Adding the possibility to choose an exact time, instead of just a date. That can be useful to have strict deadline, such as midnight anywhere on earth, etc. Solved by: #1616
