CHAPTER 8 ■ EDITING THE CALENDAR WITH AJAX AND JQUERY "deserialize" : function(str){.}, "urldecode" : function(str) {.} }; Fixing Timezone Inconsistencies You aren’t passing a time or timezone to the Date object, so that object will default to midnight Greenwich Mean Time (00:00:00 GMT). This can cause your dates to behave unexpectedly for users in different timezones. To address this problem, you’ll need to adjust the date by the timezone offset using two built-in Date object methods: .setMinutes() and .getTimezoneOffset(). The return value of .getTimezoneOffset() is the difference in the number of minutes between GMT and the user’s timezone. For instance, the return. | CHAPTER 8 EDITING THE CALENDAR WITH AJAX AND JQUERY deserialize function str . urldecode function str . Fixing Timezone Inconsistencies You aren t passing a time or timezone to the Date object so that object will default to midnight Greenwich Mean Time 00 00 00 GMT . This can cause your dates to behave unexpectedly for users in different timezones. To address this problem you ll need to adjust the date by the timezone offset using two built-in Date object methods .setMinutes and .getTimezoneOffset . The return value of .getTimezoneOffset is the difference in the number of minutes between GMT and the user s timezone. For instance the return value of .getTimezoneOffset in Mountain Standard Time -0700 is 420. Using .setMinutes you can add the value of the timezone offset to the Date object which will return the date to midnight on the given day no matter what timezone the user is in. You can make that adjustment using the following bold code fx initModal function . boxin function data modal . boxout function event .
