| # globalization.isDayLightSavingsTime |
| |
| Indicates whether daylight savings time is in effect for a given date |
| using the client's time zone and calendar. |
| |
| navigator.globalization.isDayLightSavingsTime(date, successCallback, errorCallback); |
| |
| ## Description |
| |
| Indicates whether or not daylight savings time is in effect to the |
| `successCallback` with a `properties` object as a parameter. That object |
| should have a `dst` property with a `Boolean` value. A `true` value |
| indicates that daylight savings time is in effect for the given date, |
| and `false` indicates that it is not. |
| |
| The inbound parameter `date` should be of type `Date`. |
| |
| If there is an error reading the date, then the `errorCallback` |
| executes. The error's expected code is `GlobalizationError.UNKNOWN\_ERROR`. |
| |
| ## Supported Platforms |
| |
| - Android |
| - BlackBerry WebWorks (OS 5.0 and higher) |
| - iOS |
| - Windows Phone 8 |
| |
| ## Quick Example |
| |
| During the summer, and if the browser is set to a DST-enabled |
| timezone, this should display a popup dialog with text similar to |
| `dst: true`: |
| |
| navigator.globalization.isDayLightSavingsTime( |
| new Date(), |
| function (date) {alert('dst: ' + date.dst + '\n');}, |
| function () {alert('Error getting names\n');} |
| ); |
