timezone

问题 I am trying to create a date object from a string. I get date in ISO format except milliseconds part like "2012-01-30T16:23:12" Results differ when I run following code in IE, Chrome and Firefox (Link to Fiddle) currentDate = "2012-01-30T16:23:12"; var date = new Date(currentDate); alert(date); IE and Chrome considers the string as UTC but firefox considers in local time zone. Is there any generic way to get around it except for checking user agent everywhere? 回答1: You could try appending the

问题 I would like to start by saying that I've read several threads similar to this one, but none of them really solved my problem. I would also like to state that I've tried to use SimpleDateFormat and joda.DateTime without any success. The problem is the following: I have a Calendar object that holds the information about a specific date: 2008-04-30T00:00:00Z When using the calendar.getTime() method I can get different results because I know that that method is looking for the local value Thus:

问题 My server is in Dallas. I'm in New York City.. and both PHP and MySQL have configuration variables for setting the timezone. How do I get them all to work together? What dates should I store in MySQL? How do I get PHP to handle changing the date based on the user's preference? Bear in mind: I don't think I'm ever having PHP explicitly set the date, it's always using "NOW()" in queries.. however I foresee the need to do this. How would this be done? I'm hoping SO's experience can help me out

问题 I specified config.time_zone in my Rails app, but the retrieved times in form fields still render as the UTC (which creates problems on updates). Shouldn't this be converted to local time in the specified zone? /config/application.rb (relevant lines only): module ExampleSite class Application < Rails::Application config.time_zone = 'Central Time (US & Canada)' end end /events/edit.html.erb (full file): <h1>Edit This Event</h1> <%= form_for(@event) do |f| %> <%= render 'fields', :f => f %>

问题 I need to write a script for publishing .ICS files. I've read that it's difficult to do this right, either because some calendar clients are buggy (lots of people claim Google Calendar is extremely buggy especially regarding time zones) or because developers aren't following the spec properly. I only need to do this for North America but I do have to account for DST (keeping in mind places like Arizona, parts of which observe DST and parts of which don't). Can anyone answer these questions?

问题 I need to get time difference between two dates in different time zones. Currently I am doing this: Calendar c1=Calendar.getInstance(TimeZone.getTimeZone("EDT")); Calendar c2=Calendar.getInstance(TimeZone.getTimeZone("GMT")); String diff=((c2.getTimeInMillis()-c1.getTimeInMillis())/(1000*60*60))+" hours"; new AlertDialog.Builder(this).setMessage(diff).create().show(); I get 0 hours. What am I doing wrong? 回答1: getTimeInMillis() returns the number of milliseconds since the epoch in UTC . In

问题 I have data points whose abscissas are datetime.datetime objects with a time zone (their tzinfo happens to be a bson.tz_util.FixedOffset obtained through MongoDB). When I plot them with scatter() , what is the time zone of the tick labels? Changing the timezone in matplotlibrc does not change anything in the displayed plot (I must have misunderstood the discussion on time zones in the Matplotlib documentation). I experimented a little with plot() (instead of scatter() ). When given a single

问题 I have a timestamp the user enters in GMT. I would then like to display that timestamp in gmt, cet, pst, est. Thanks to the post below I have made, which works perfectly! public static function make_timezone_list($timestamp, $output='Y-m-d H:i:s P') { $return = array(); $date = new DateTime(date("Y-m-d H:i:s", $timestamp)); $timezones = array( 'GMT' => 'GMT', 'CET' => 'CET', 'EST' => 'EST', 'PST' => 'PST' ); foreach ($timezones as $timezone => $code) { $date->setTimezone(new DateTimeZone(
