i am trying to add a time to current date.
example:
i have this time : 05:17 am
i want to add this time current date by replace current time by this time.
if current date and time is : 10-09-2021 11:30 am
i want to add current date and replace time by my specific time => output for example above: 10-09-2021 05:17 am
i am trying:
var time = this.timeInput;
new Date().getTime() + convertTimeToInt(time);
// in this case we add current time to my input time, i don't want this.
convertTimeToInt() is a method that convert time to int.
Any idea?
This will do
let time = '05:17 pm';
let splittedTime = time.split(' ');
let [hours, minutes] = splittedTime[0].split(':');
let isAm = splittedTime[1] === 'am'; // in europe we don't use am, the hours goes from 0 to 24
var date = new Date(); // now
console.log('before ' + date);
let hourToAdd = 0;
if(+hours === 12) {
if(isAm) {
hourToAdd = - 12; // at midnight we dont add +12 nor +0, we want 12am to be 0 hours
} else {
hourToAdd = 0;
}
} else {
hourToAdd = isAm ? 0 : 12;
}
// use setHours to set time
date.setHours(+hours + hourToAdd, +minutes, 0, 0);
console.log('after ' + date);
Output:
let time = '12:17 pm';

UPDATE: without am/pm, you can use
let time = '05:17';
let [hours, minutes] = time.split(':');
var date = new Date(); // now
console.log('before ' + date);
date.setHours(+hours, +minutes, 0, 0); // set hours/minute
console.log('after ' + date);
Output:

[LOG]: "after Fri Sep 10 2021 05:17:00 GMT+0200
