dst

I'm trying to represent a UTC timestamp in different timezones using PHP's date_default_timezone_set function. Daylight saving has just kicked in here (NZ) and in Australia, and I'm getting mixed results... Here's some test code... date_default_timezone_set('NZ'); print '<p>NZ time is ' . date('Y-m-d H:i:s T (I)') . '</p>'; date_default_timezone_set('Australia/NSW'); print '<p>NSW time is ' . date('Y-m-d H:i:s T (I)') . '</p>'; date_default_timezone_set('Australia/North'); print '<p>NT time is ' . date('Y-m-d H:i:s T (I)') . '</p>'; date_default_timezone_set('Australia/South'); print '<p>SA

I need to know whether the period defined by: DateTime start; DateTime end; has a DST inside. I am iterating over collection of periods defined by {start,end} and shifting start and end 24 hours forward in every iteration. The resulting period starts at midnight and ends at 1 ms before next midnight. I found that if the period has a daylight saving point inside the shift produces incorrect result, e.g: having: Duration targetDuration = new Duration(24*60*60*1000L-1); DateTime start = new DateTime("2012-03-10T00:00:00.000-08:00"); DateTime end = new DateTime("2012-03-10T23:59:59.999-08:00");

I a newbie to java and hence haven't been able figure this out since quite some time. I am using Windows XP and the machine is set to TimeZone: Eastern Time (US & Canada) . I have a Java application, which takes the current system time and timezone info and writes a string like: 20101012 15:56:00 EST, to a file. The last piece of Date above, i.e.: the timezone, changes from EST to EDT as i change my system date. Being precise: From November(eg: Nov2009) to March (Mar 2010), it is EST, otherwise EDT. EST is what I want ALWAYS and not EDT. Is there any particular class / function, by which I can

I have a Java app that needs to be cognizant of the time zone. When I take a Unix epoch time and try to convert it into a timestamp to use for an Oracle SQL call, it is getting the correct timezone, but the timezone "useDaylightTime" value is not correct, i.e., it is currently returning "true", when we are NOT in DST (I am in Florida in TZ "America/New_York"). This is running on Red Hat Linux Enterprise 6, and as far as I can tell, it is correctly set up for the timezone, e.g. 'date' returns: Wed Nov 28 12:30:12 EST 2012 I can also see, using the 'zdump' utility, that the current value for

I have a quartz cron trigger that looks like so: <bean id="batchProcessCronTrigger" class="org.springframework.scheduling.quartz.CronTriggerBean"> <property name="jobDetail" ref="batchProcessJobDetail" /> <property name="cronExpression" value="0 30 2 * * ?" /> </bean> How should I solve this, if I have several configurations that happen within the 2-3am period? Is there an accepted best practice? Relevant link: http://www.quartz-scheduler.org/docs/faq.html#FAQ-daylightSavings Basically it says "Deal with it." But my question is how! I solved it using a separate trigger that only fires (an hour

Does php's date_default_timezone_set adjust to daylight saving? I have this code, and wonder if it will always result in the correct Stockholm time? date_default_timezone_set('Europe/Stockholm'); $timestamp = date("Y-m-d H:i:s"); Yes this should always result in the right time. PHP doesn't handle DST automatically. You have to check if (date('I', time()) == 1) ... the time is in DST mode ("0" = not) Then you should adust time accordingly. (Note: 'I' in capital. I have just checked it and it works.) As long as your timezone is listed in the following link, timestamp should be relative to the
