Syntax

dateObj.getTimezoneOffset()

Return value

A number representing the time-zone offset, in minutes, from the date based on current host system settings to UTC.

Description

The time-zone offset is the difference, in minutes, from local time to UTC.

Note that this means that the offset is positive if the local timezone is behind UTC, and negative if it is ahead. For example, for time zone UTC+10:00 (Australian Eastern Standard Time, Vladivostok Time, Chamorro Standard Time), -600 will be returned.

Current Locale	UTC-8	UTC	UTC+3
Return Value	480	0	-180

The time zone offset returned is the one that applies for the Date that it's called on.

If the host system is configured for daylight saving, the offset will change depending on the date and time that the Date represents and that daylight saving applies.

Examples

Using getTimezoneOffset()

// Get current timezone offset for host device
let x = new Date();
let currentTimeZoneOffsetInHours = x.getTimezoneOffset() / 60;
// 1

// Get timezone offset for International Labour Day (May 1) in 2016
// Be careful, the Date() constructor uses 0-indexed months, so May is
// represented with 4 (and not 5)
let labourDay = new Date(2016, 4, 1)
let labourDayOffset = labourDay.getTimezoneOffset() / 60;
