timezone

问题 Most sites need some way to show the dates on the site in the users preferred timezone. Below are two lists that I found and then one method using the built in PHP DateTime class in PHP 5. I need help knowing which of these would be the best to attempt to use when trying to get the UTC offset from the user on register. One: <option value="-12">[UTC - 12] Baker Island Time</option> <option value="-11">[UTC - 11] Niue Time, Samoa Standard Time</option> <option value="-10">[UTC - 10] Hawaii

问题 Goal: Find the local time and UTC time offset then construct the URL in following format. Example URL: /Actions/Sleep?duration=2002-10-10T12:00:00−05:00 The format is based on the W3C recommendation: http://www.w3.org/TR/xmlschema11-2/#dateTime The documentation says: For example, 2002-10-10T12:00:00−05:00 (noon on 10 October 2002, Central Daylight Savings Time as well as Eastern Standard Time in the U.S.) is equal to 2002-10-10T17:00:00Z, five hours later than 2002-10-10T12:00:00Z. So based

问题 I need to format date time in java for provided time zone. E.g. mm/dd/yyyy for US and dd/mm/yyyy for DE. I have time zone and i can get zoneId, can someone help me. Many thanks. 回答1: Use the modern Java date and time classes for everything that has got to do with dates or times. DateTimeFormatter usFormatter = DateTimeFormatter.ofLocalizedDate(FormatStyle.SHORT) .withLocale(Locale.US); System.out.println(date.format(usFormatter)); DateTimeFormatter deFormatter = DateTimeFormatter

问题 Question 1/3: I have a number of MySQL databases to connect to and want to ensure time consistency across queries. So for example, one of these servers is currently in the CDT timezone. > select CURRENT_TIMESTAMP, @@system_time_zone, @@global.time_zone, @@session.time_zone; +---------------------+--------------------+--------------------+---------------------+ | CURRENT_TIMESTAMP | @@system_time_zone | @@global.time_zone | @@session.time_zone | +---------------------+--------------------+----

问题 There is a relevant question about how ToUniversalTime works. But the relevant information about time conversions tells me there are relevant databases for time conversion in the past. My question is how can ToUniversalTime forecast and knows when will be the DST change in 2070 for example? 回答1: My question is how can ToUniversalTime forecast and knows when will be the DST change in 2070 for example? It can't. It doesn't have any special insight into the future of what the governments of our

问题 I've worked with Oracle's timestamp with time zone before, but this time I'm getting values as strings and trying to load them to the database. When converting the string, I end up with a value in the database time zone. This is odd, but workable if it adjusted the time accordingly yet it doesn't. See below: SELECT TO_CHAR(systimestamp AT TIME ZONE 'Canada/Pacific', 'HH24:MI:SS Mon DD, YYYY TZD') now_pst , TO_CHAR(systimestamp AT TIME ZONE 'Canada/Eastern', 'HH24:MI:SS Mon DD, YYYY TZD') now

问题 I am receiving the correct unix time that I use in my html page in my javascript. However, when I view or alert the unixtime, what happens is that the date is adjusted based on my desktop's current timezone, but I need the DateTime to be without the timezone. This is how I pass the data in my javascript, one of the many ways I use the unixtime: <script type="text/javascript"> $(document).ready(function(){ var a = <?php echo "1434203820"; // an example only?>; var date = new Date(a); alert

问题 I have an application that automates email communications between my companies service desk and customers. When the application needs to reply to an existing email, i use FindItems to get the email and then i load the properties i need, then i use (CreateReply) to get the response email i need to send. The strange behavior is as follows: The email i need to reply to has a correct SentDateTime and timezone (+4 GMT) but when i create a reply from it the sent date of the "replied to email"

问题 I have retrieved a list of all the time zones using this function and storing them in an array : timeZoneElements = [NSTimeZone knownTimeZoneNames] ; I want to get the list of abbreviations , for example : GMT+1 … is there any easy and quick way to do that ? Many thanks Edit 1 : This solution shows the timezones like follows : Asia/Beirut … therefore i need to show instead the GMT+2 label .. 回答1: Try This, NSMutableArray *timeZoneArray = [[NSMutableArray alloc] initWithArray:[NSTimeZone

问题 The below code when run with JDK5(1.5.0_09) prints Fri May 03 00:00:00 GMT 3912 5/3/12 5:30 AM and when run with JDK6(1.6.0_23) prints Fri May 03 00:00:00 IST 3912 5/3/12 12:00 AM Obviously the difference is because of the timezone used then the Date object is created. But doesn't this cause problems for existing code when the JDK is upgraded? Is this behavior documented somewhere or am I missing something? class TimeTest { public static void main(String[] args) { Date d = new Date(2012, 04,
