dst

问题 +I have a time tracking app that uses joda DateTime to persist Start/End time with ORM-lite. ORM-lite stores a Joda DateTime as long in database by using its millis. Joda DateTime.getMillis() returns Milliseconds in UTC. In a few days we switch from daylight-saving time to normal time and I'm not 100% sure if my app will handle this correctly. To test it I tried to disable the "Automatic date & time (Use network-provided time)" setting of my device and changed the date to one that has normal

问题 I'm getting strange behavior from Joda Time when trying to get the seconds since midnight on a DST switch day. My code: public static void main(String[] args) { DateTimeZone timeZone = DateTimeZone.getDefault(); System.out.println(timeZone); DateTimeFormatter dateFormatter = DateTimeFormat.shortDate(); DateTimeFormatter dateTimeFormatter = DateTimeFormat.fullDateTime(); LocalDate date = new LocalDate(2016, 10, 29); for (int i=0; i<3; i++) { System.out.println(); System.out.println

问题 I've read through a few questions about this here on s.o. and none seem to ask or answer the question very bluntly: $ts_today = mktime( 0, 0, 0, date('m'), date('d'), date('Y') ); is this daylight saving aware? if not, how do i make mktime() daylight saving aware? 回答1: ~There's plenty of discussion of this on the PHP site itself, and some useful examples. In short, newer versions of PHP take account of DST as part of the timezone handling functionality 回答2: The last argument specifies whether

问题 I have a Java program that runs on a linux virtual machine as a cron job. Currently there's an issue, the following line is used as part of logging to store the current date and time: String date = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss").format(new Date()); After daylight savings today, it was determined the system date was not set up correctly as it did not update. After fixing this using the following command, and restarting the linux environment the date is now correct and updated for

问题 Let's say I'm given a string such as this: "2009-4-9" , meaning April 9th, 2009. Assuming for starters, that I am only concerned with local time (I have concerns about other time zones as well, but I'll tackle the easy stuff first). What is the best way to know if Daylight Savings was in effect at that time? You can assume that the system has the properly updated timezone files such as /etc/localtime and I am interested in portable solutions. Either c or c++ are acceptable as well. You can

问题 I know there is a method to determine if a certain time is on Daylight Savings Time ( Time.now.dst? ) but is there a method to give us the next date when Daylight Savings will change? For example, Google returns Sunday, November 1 as the next Daylight Savings Time change in 2015. 回答1: Since these are dates that are based on other values, like the timezone you are working with, it requires a module like ActiveSupport/TZInfo. require 'active_support/core_ext/time/zones' tz = TZInfo::Timezone

问题 I am making an events app in django. In that I need to make a copy of one event object (row/entry in DB) into another. It creates another object with same details. This event object involves timezone and Day light Saving. I am facing problems during DST. I have applied time delta of 5 days during copying of objects. In normal days Event object 1 date: Nov. 10, 2014 10:36 a.m. Event object 2(copy of 1) date: Nov. 15, 2014 10:36 a.m. This OK..! But in DST days I don't want this 1 hr change.

问题 I need to configure DST time for some application running in a server which is in Fiji. OS level time has configured properly : Tue Nov 11 17:28:51 **FJST** 2014 (FJST - Fiji Summer Time) I have changed the log4j.xml configuration as follow and tried: <layout class="org.apache.log4j.EnhancedPatternLayout"> <param name="ConversionPattern" value="%d{ISO8601}{GMT+13} %-5p %c{1} [%x] [%t] - %m%n" /> This works bit fine, but this can be a workaround only, can't be a solution. Following two issues

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. I want this schedule to works fine regardless of the DST changes. If I schedule this

问题 This does not work: t = os.path.getmtime(filename) dTime = datetime.datetime.fromtimestamp(t) justTime = dTime.timetuple() if justTime.tm_isdst == 0 : tDelta = datetime.timedelta(hours=0) else: tDelta = datetime.timedelta(hours=1) What happens instead is that the conditional always equals 1, despite some of the timestamps being within daytime savings time. I am trying to make a python call match the behavior of a c-based call. 回答1: To find out whether a given timestamp corresponds to daylight
