Saving a change request after running a check conflicts causes error Invalid date on Conflict last run field. This happens for a user for who the date format is set to anything other than system date format.

On a Jakarta OOB instance version glide-jakarta-05-03-2017__patch0-05-18-2017

1. Set current user profile Date Format to anything other than system format. For example, as an ITIL user set the date format as dd-mm-yyyy
2. On a Change Request, set Planned Dates that generate a conflict, then Save record. This works correctly as expected.
3. After reload, navigate to Conflicts tab, and click on Check Conflicts
4. This changes the field Conflicts last run date time value.
5. Save the change record.

Result: Invalid date error appears under Conflicts last run date time field.
