Add non-repeating minute/second scale

Hi Team,
We are using single Minute scale in DHTML Gantt but after an interval of 1440 minutes scale is repeating itself. Our requirement is to add support for tasks with time <= 99999 minutes therefor if any task with 1500 minutes allocated time is added then scale should be able to show 1500 minutes as per the task end time.

Hello Amit,
If you use the minute scale, after reaching the 1430 minute, you get the next day. This is expected behavior because this is how the dates work in Javascript.
The easiest way for you would be to modify the template that displays the values for the scale cells.

You can show the number of the scale cell instead of the actual value:

And it works the same way regardless of the scale:

Another way is to calculate the duration in minutes starting from the initial date:
