阅读更多关于 Java 8 Offset Date Parsing

问题 I need to parse a String in the following format 2015-01-15-05:00 to LocalDate(or smth else) in UTC. The problem is that the following code: System.out.println(LocalDate.parse("2015-01-15-05:00", DateTimeFormatter.ISO_OFFSET_DATE)); outputs 2015-01-15 ignoring the offset. The desired output is 2015-01-16 Thanks in advance! 回答1: The simplest answer is to use OffsetDateTime to represent the data, but you need to default the time: DateTimeFormatter fmt = new DateTimeFormatterBuilder() .append

阅读更多关于 FullCalendar: Default timezone irrespective of client's location

问题 I am trying to create an appointment-scheduling application with fullcalendar . I want to represent time-slots on the calendar in only one timezone(i.e., EST) across all locations.

阅读更多关于 Java convert millisecond timestamp to date with respect to given timezone

I have seen many resources on this but one thing I cant get is when converting the millisecond timestamp, how I add a corresponding time zone, during the conversion process. Date date = new Date(Long.valueOf(dateInMil*1000L); SimpleDateFormat myDate = new SimpleDateFormat("EEE, MMM d, ''yy"); String formatted = myDate.format(date); Now if I have a time zone/offset in string formate i.e. "-04:00" or "+2:00" how to apply it to the above so I can get the proper date ? I was doing a similar thing in my previous project.You can use setTimeZone method of SimpleDateFormat class. Something like this :

How do I convert UTC/ GMT datetime to CST in Javascript? (not local, CST always)

阅读更多关于 How do I convert UTC/ GMT datetime to CST in Javascript? (not local, CST always)

问题 I have a challenge where backend data is always stored in UTC time. Our front-end data is always presented in CST. I don't have access to this 'black box.' I would like to mirror this in our data warehouse. Which is based in Europe (CET). So "local" conversion will not work. I'm wondering the simplest, most straightforward way to accurately convert UTC time (I can have it in epoch milliseconds or a date format '2015-01-01 00:00:00') to Central Standard Time. (which is 5 or 6 hours behind

Daylight Saving Time start and end dates in Ruby/Rails

阅读更多关于 Daylight Saving Time start and end dates in Ruby/Rails

I'm working on a Rails app where I need to find the Daylight Saving Time start and end dates given a specific offset or timezone. I basically save in my database the timezone offset received from a user's browser( "+3" , "-5" ) and I want to modify it when it changes because of daylight saving time. I know Time instance variables have the dst? and isdst methods which return true or false if the date stored in them is in the daylight saving time or not. > Time.new.isdst => true But using this to find the Daylight Saving Time beginning and end dates would take too many resources and I also have
