Hello
I am newbe in Jira (5.2) and I would like to add custom field to my screen. I used custom field as text type and I want to allow users to enter in this field only data in the format XX:YY (which will be represented time eg. 21:00, 07:10 ...). I need to control that users can't enter an invalid value eg. 33:45, 88:77 .... How can I do that in Jira? Thanks for your reply.
