[FIX] web: correct date and datetime parsing.

When creating a new Date object at a specific date, this date is treated as a UTC datetime
then normalized to the browser timezone. This can lead to a change of Year/Month/Day depending
of the chosen date. Using a date of a leap year date for date parsing and forcing UTC date for
datetime parsing correct the month-switch errors in all timezones
