Blocking time in 15-min interval

Good day,

I want to be able to block timeslot in 15-min intervals. We are using a custom view to display the scheduler with 15-min intervals. How should the time_points value be passed to the blockTime() API.

Thank you very much.

block time api accepts start and end time of blocking zone, as count of minutes from the day start, so it can be rounded to 15-minutes limit, if necessary.

scheduler.blockTime(6, [860,860+15]); //blocks 8.00 - 8.15

Tried this, but seems I needed to add 15 more

scheduler.blockTime(6, [860,860+30]); //blocks 8.00 - 8.15
