timezone

问题 I have a unix timestamp in PHP : $timestamp = 1346300336; Then I have an offset for timezones which I want to apply. Basically, I want to apply the offset and return a new unix timestamp. The offset follows this format, and unfortunately can't be changed due to compatibility with other code: $offset_example_1 = "-07:00"; $offset_example_2 = "+00:00"; $offset_example_3 = "+07:00"; I tried: $new_timestamp = strtotime($timestamp . " " . $offset_example_1); But this does not work unfortunately :(

问题 I'm using postgresql to store some dates on a database. In my application it is fundamental that it is completely aware of timezones and I was conducting some basic tests, between, client, server and database.

问题 Can anybody explain me following behaviours: $end = new DateTime("2015-03-01", new DateTimeZone("Europe/Berlin")); $start = new DateTime("2015-02-01", new DateTimeZone("Europe/Berlin")); $diff = $start->diff($end); //result: DateInterval Object ( [y] => 0 [m] => 0 [d] => 28 [h] => 0 [i] => 0 [s] => 0 [invert] => 0 [days] => 28 ) If I don't use a timezone or Europe/Berlin I get wrong time diffs. 28 days is indeed correct, but in this case it's a month. $end = new DateTime("2015-03-01", new

问题 Do filesystems store time zone information along with the file information? I ran into a weird bug where I do the following snippet and I get different time zone printed out. import DateTime #zope's module for each in os.listdir("director"): print DateTime.DateTime(os.stat(each)[8]) #Why is it mixed up? Foo 12:00:00 US/Eastern Bar 12:00:00 GMT -4 It started to happen after Daylight Saving changes were made. I see Eastern and GMT -4 both. IIRC Linux doesn't store the time stamp information,

问题 I have a Oozie application that suppose to respect Daylight savings. However my schedules are complex so I can't represent them as Expression Language functions such as ${coord:days(2)} . Therefore I need to use CRON expressions. One example of schedule is every week on weekdays at 13:30 PM (resulting cron expression for Oozie "30 13 * * 2-6" with no time zone adjustment) America/Los Angeles timezone.

问题 I have a client side JavaScript that generates a date in JavaScript( new Date(2007,5,1) ). I need this date passed through to a hidden field that the code behind can access. My issue is that when the hidden field is converted into a DotNet datetime, the time is incorrect. This is because the JavaScript is including timezone info from the client browser.
