问题 As I know, we can use below to roughly convert a UNIX timestamp to a VB Date CDate([UNIX timestamp]/ 60 / 60 / 24) + "1/1/1970" However, the time zone and daylight information are not considered. Time zone is not a big deal. But I cannot get the daylight bias information for a specific UNIX timestamp. Though, daylight bias of Date 1/1 is obviously different from Date 6/1, however, for Date 3/12 or Date 11/5, the daylight bias calculation is very complex. I tried several APIs, like

问题 If Cron has a job scheduled to run at 2 am and one at 3 am how would those jobs be affected by daylight savings time? When the time shifts back an hour does the time go from 2:59:59 am to 2:00:00 am directly? Meaning that the 2 am job would run twice and the 3 am job would run once? Or is does the time first change to 3:00:00 am and then 2:00:00 am causing both jobs to run twice? When the time shifts forward an hour does the time go from 1:59:59 am to 3:00:00 am causing the 2 am job to not

问题 I need to parse the date/time string, to add the raw offset and convert it according to local time zone. The date time that I get from server is in this format : "05-25-2012 02:30 PM" This format is not parsed by : HttpDateParser.parse(time) method But HttpDateParser does parse this format : "25-MAY-2012 02:30 PM" Can you tell me, how should I parse "05-25-2012 02:30 PM" String in BB to get a long value. I have 1 more problem, I need to display time zone in format GMT, IST, but all I can

问题 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

问题 In api call response I'm getting dates in different timezone. I want to convert it to user's local timezone plus user can select any timezone from the list of ios timezone. This is all local. We would never be sending selected user timezone to server. And while making any api call lets say i am creating an event with selected start date in a picker. I should send it global timezone not with the user selected timezone because it is local to the app. Currently I am changing defaultTimeZone on

问题 I've run the following in the console on Firefox (version 21) and I'm getting results I don't expect. new Date(1362891600000); var date = new Date(1362891600000); var time = date.getHours(); new Date(date.setHours(date.getHours() + 24)); The result really throws me for a loop. The first date shows up as Eastern Daylight Time, while the second one shows up with Eastern Standard Time. It's totally backwards. This does not happen with IE or with Chrome. What's going on here? 回答1: This is

问题 I run an application as a service on a server and then I have multiple clients connect to that service. I display the exact server time on each of the client Window form application and because of that I need a mechanism to detect any time change on the server so that I can send it to the client to display. Looking over the MSDN I found SystemEvents.TimeChanged , I thought I'm in luck because when testing with the code below with Visual Studio everything works great: SystemEvents.TimeChanged
