被刻印的时光 ゝ 提交于 2019-12-23 09:33:13
问题 I am working on a php code as shown below which has air_date which I want to be changed when different timezone is selected from UI . Php code: $cols = array( 'e.description_' . $opp_lang . ' as translation', 's.air_date', // This is the entry point of air_date and its been used everywhere. 'e.program_id', ); Logic I have used for timezone: function tz_translations( $lang = 'en' ) { $tz_translations = [ 'en' => [ 'PST' => [ 'label' => 'PT', 'diff' => 'subtract 3 hours', ], 'EST' => [ 'label'

Android AlarmManager and DST/Timezone/Time change?

送分小仙女□ 提交于 2019-12-23 09:30:45
问题 I'm coding an alarm clock application, and i would like to know what happens, when I set some alarm with AlarmManager for example at time 2:59am (this is not time of my alarm, this is only time WHEN i set some alarm), and at 3:00am there will be automatic time change from summer time to winter (DST). What happens with my scheduled alarm? I found nothing in docs, and it's not so easy to test, at least I must change dates and wait few hours...I'm not so patient ;) Next problem - I was also

How to find next day's Unix timestamp for same hour, including DST, in Python?

て烟熏妆下的殇ゞ 提交于 2019-12-23 09:18:05
问题 In Python, I can find the Unix time stamp of a local time, knowing the time zone, like this (using pytz): >>> import datetime as DT >>> import pytz >>> mtl = pytz.timezone('America/Montreal') >>> naive_time3 = DT.datetime.strptime('2013/11/03', '%Y/%m/%d') >>> naive_time3 datetime.datetime(2013, 11, 3, 0, 0) >>> localized_time3 = mtl.localize(naive_time3) >>> localized_time3 datetime.datetime(2013, 11, 3, 0, 0, tzinfo=<DstTzInfo 'America/Montreal' EDT-1 day, 20:00:00 DST>) >>> localized_time3

Testing correct timezone handling

问题 We are working with large amounts of data, all tagged in UTC (in Java). Between reading this data, storing it in a database and getting it out again, it happened, that some data was off one hour during daylight saving time. As UTC has no concept of daylight saving time this was clearly a bug within the software. Once known, it's easy to fix. However, it'd be nice to have some unit/integration tests that work regardless of the current time difference - e.g. I'd like to change the local time

Importing ICS into Google Calendar with correct timezone

血红的双手。 提交于 2019-12-23 08:54:12
问题 I'm trying to import a simple ics file into Google calendar. However, even though I have the timezone specified, Google calendar still imports the wrong event time. (Although it does say that the wrong time is in the correct timezone.) Here is a sample of my ics file: BEGIN:VCALENDAR BEGIN:VEVENT DESCRIPTION: Test_Description DTEND;TZID=US-Pacific:20140606T180000 DTSTART;TZID=US-Pacific:20140606T170000 LOCATION:Test_Location SUMMARY:Test_Summary UID:20140606T150000@NL END:VEVENT END:VCALENDAR

How to set Timezone per thread? [closed]

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I know we could change the current culture for the current thread. And I know we couldn't get TimeZoneInfo from the CurrentCulture because one culture may has many TimeZones like USA But to use the same technique

问题 I was wondering if i can get somewhere the default code for time zone selection list for android version 2.3.3? 回答1: String[] ids=TimeZone.getAvailableIDs(); for(int i=0;i<ids.length;i++) { System.out.println("Availalbe ids.................."+ids[i]); TimeZone d= TimeZone.getTimeZone(ids[i]); System.out.println("time zone."+d.getDisplayName()); System.out.println("savings."+d.getDSTSavings()); System.out.println("offset."+d.getRawOffset()); ////////////////////////////////////////////////////

How quickly is CRON triggered?

青春壹個敷衍的年華 提交于 2019-12-23 08:03:46
问题 First Example Suppose I have a CRON job 30 2 * * * .... Then this would run every time when it is 2:30 at night (local time). Now suppose I have the time zone Europe/Germany and it's 2017-10-29 (the day when DST is switched). Then this CRON job would run twice, right? Second Example Suppose I have the time zone Europe/Germany and the CRON job 30 11 * * * .... As Germany never had a DST change at 11:30, this will not interfere. But the user could change the local time. To be super clear: This

Java 8, why not a ZonedTime class?

老子叫甜甜 提交于 2019-12-23 07:46:08
问题 I found that Java 8 doesn't have an equivalent to ZonedDateTime but to work only with Time (a ZonedTime class or something like that). I know they included the OffsetTime class, but it only stores the offset. Storing time zones along with date and time, instead of just store the offset, helps to deal with daylight savings easier. I'm not asking you to give me alternatives, I know there are many approaches; I'm just wondering why such class was not included, is it a design issue? or they just

Getting incorrect time leading by 1 hour with Europe/Moscow timezone

社会主义新天地 提交于 2019-12-23 07:45:59
问题 For our Russia tenant we are using "Europe/Moscow" timezone. But we are getting time with 1 hour ahead of the correct time. Europe/Moscow is UTC+3 hours. But when I am print date formated with Europe/Moscow timezone getting 1 hour ahead of the correct time. Thanks, Syamala. 回答1: I notice that there was a legislative change to Russian time zone definitions in October 2014; chances are that your JRE simply doesn't know about it yet. The Java Timezone Updater Utility should be able to fix this
