Javascript Date setUTCHours(hours)

Introduction

Javascript Date setUTCHours(hours) sets the UTC date's hours. 

dateObj.setUTCHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])

Parameters

  • hoursValue - An integer between 0 and 23, representing the hour.
  • minutesValue - Optional. An integer between 0 and 59, representing the minutes.
  • secondsValue - Optional. An integer between 0 and 59, representing the seconds. If you specify the secondsValue parameter, you must also specify the minutesValue.
  • msValue - Optional. A number between 0 and 999, representing the milliseconds. If you specify the msValue parameter, you must also specify the minutesValue and secondsValue.

Return value

The number of milliseconds between January 1, 1970 00:00:00 UTC and the updated date.

If a parameter is outside of the expected range, setUTCHours() updates the date accordingly.

For example, if you use 100 for secondsValue, the minutes will be incremented by 1, and 40 will be used for seconds.

Setting the hours to a number greater than 23 also increments the day of the month. 

var d = new Date();
console.log(d);//from w  w w .  ja  va 2s .  co  m
d.setUTCHours(8);
console.log(d);

Set the time to 15:35:01 UTC time 

var d = new Date();
d.setUTCHours(15, 35, 1);//from w  w  w  . j  av  a2s. com
console.log(d);

Set the time to 48 hours ago, using UTC methods: 

var d = new Date();
d.setUTCHours(d.getUTCHours() - 48);/* ww  w. ja v a 2  s. c  o m*/
console.log(d);
