How/What syntax to use to enter time for a checklist task in Trello so as to have them drawn on a Ganttify chart?
To set a start date for checklist's items you can add: 'start: 12/25/2014 01:00PM' to it's description. So this setting consists of three parts. Part one is the text fragment 'start:' then part two is the date '12/25/2014' (IMPORTANT:it's month/day/year!) and part three (which is optional) is the time '01:00PM'.
You can also add: 'duration:4d' or 'duration:2.5h' this will show a colored bar with a duration of 4 days or 2.5 hours for example
