fix(timepicker): fix date overflow on short months

[a-mcc]

Change year, month, date setting on time change to be atomic, preventing overflows for short months.
When the time is decremented before midnight such that the date would go back a day there is code to reset the year, month and day, in that order. this causes an issue with shorter months, for example February or April, when on the 1st of these months and the date goes back a day, calling date.setMonth(monthIndex) causes an overflow to the next month.
For example, February 1st 00:00:00 -> January 31st 23:00:00
Upon calling date.setMonth(1) we are essentially setting the date to February 31st which rolls over a few into March. date.setDate(1) is then called which results in the Date object representing March 1st, instead of February 1st.
The fix is a simple one, date.setFullYear accepts arguments for year, month and day, allowing these to be set atomically and prevents this overflow issue.

Closes #5766
