#Date and time as String to Long (millis):
String dateTimeString = "2021-09-12T16:55:18.000Z";
DateTimeFormatter formatter = DateTimeFormatter
.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDateTime localDateTime = LocalDateTime
.parse(dateTimeString, formatter);
Long dateTimeMillis = localDateTime
.atZone(ZoneId.systemDefault())
.toInstant()
.toEpochMilli();You can then use the number of milliseconds to convert it to a date object:
var msec = Date.parse("March 21, 2012");
var d = new Date(msec);
document.getElementById("demo").innerHTML = d;Copyright © 2021 Codeinu
