This PR fixes issue #8556 where DateInput component could not correctly display time values in controlled mode when the
valueFormatprop includes time tokens.Problem
The DateInput component, when used in controlled mode with time formats like
"YYYY-MM-DD HH:mm", would always display00:00instead of the actual time value. This happened because:useUncontrolledDateshook was hardcoded to usewithTime: falsedefaultDateParserdidn't handle time formats properlydate-string-parserhad limited format supportSolution
