Calendar datetime picker with stepMinute 15

[fairking]

I have a field which is DateTime picker with stepMinute = 15. The problem is the minutes start not from zero but from some random number (probably from the current time). So increasing or decreasing minutes make those steps like 11, 26, 41, 56. But the way I'd like and how I think it should work is to start from 00 and then increse to 15, 30, 45. I think the initial value must be somewhere to the closest interval (eg. if now is 14:35 then it must be 14:30).
I could not figure out how to fix the issue.

<Calendar id="from_date" v-model="item.fromDate" date-format="dd.mm.yy" 
:step-minute="15" :showTime="!item.allDay" />

PS. At the beginning the field is DatePicker with time 00:00. Then I switch it to DateTimePicker dynamically so showTime becomes true.

Also as an option there could be a dropdown for hour/minute input.

I just fixed this for PrimeFaces. You can probably look at my PR and fix PrimeVue the same way.

Expecting this feture! So I can remove the complex computed field from my code.

Is there any workaround for this issue?
