Why there is the difference between these two ways of getting milliseconds
gigasecond = inputDate => {
console.log(inputDate)
console.log(inputDate.getTime()) //1303689600000
console.log(
Date.UTC(inputDate.getFullYear(),
inputDate.getMonth(),
inputDate.getDate(),
inputDate.getHours(),
inputDate.getMinutes(),
inputDate.getSeconds())); //1303709400000
};
gigasecond(new Date(Date.UTC(2011, 3, 25)))
The getHours()
method returns the hour for the specified date, according to local time. Use getUTCHours()
instead.
gigasecond = inputDate => {
console.log(inputDate)
console.log(inputDate.getHours(), inputDate.getUTCHours())
console.log(inputDate.getTime()) //1303689600000
console.log(
Date.UTC(inputDate.getFullYear(),
inputDate.getUTCMonth(),
inputDate.getUTCDate(),
inputDate.getUTCHours(),
inputDate.getUTCMinutes(),
inputDate.getUTCSeconds()
)
); //1303709400000
};
gigasecond(new Date(Date.UTC(2011, 3, 25)))
