问题 I do let fullcalendar initialize normally. So it represents current date. (Midnight->midnight, 1day, 1h slots) From some other datasource I get data with timestamps. The format is "YYYY-MM-DD HH:mm" (transmitted as a string, no timezone information) So I convert that string to a moment object and test against fullcalendar.start and .end to see if it is within. moment("2016-04-07 00:00") == $('#calendar').fullCalendar('getView').end This results in false though the following command $('

问题 I try to convert from Milliseconds to string of date. However, the result is not correct as my expected. The input is milliseconds (Ex: 1508206600485 ) My time zone is UTC +10:00 ------Expected-------------------------------------------- Actual------ 01:32 (PM) 17/10/2017--------------------------------02:32 (PM) 17/10/2017 Here is the method of that public static String getDate(long milliSeconds) { SimpleDateFormat formatter = new SimpleDateFormat("hh:mm dd/MM/yyyy"); String dateString =

问题 Is there a good way to parse milliseconds since epoch (ex. 1486252500000 13 digits) formatted time into a human readable format? 回答1: DateTime does have a named constructor for millisecond since epoch https://api.dartlang.org/stable/1.24.2/dart-core/DateTime/DateTime.fromMillisecondsSinceEpoch.html DateTime date = new DateTime.fromMillisecondsSinceEpoch(1486252500000) If you want to convert it to human readable string, you can use intl package with the DateFormat class import "package:intl

问题 I have an object of ZonedDateTime that is constructed like this ZonedDateTime z = ZonedDateTime.of(LocalDate.now().atTime(11, 30), ZoneOffset.UTC); How can I convert it to LocalDateTime at time zone of Switzerland? Expected result should be 16 april 2018 13:30 . 回答1: How can I convert it to LocalDateTime at time zone of Switzerland? You can convert the UTC ZonedDateTime into a ZonedDateTime with the time zone of Switzerland, but maintaining the same instant in time, and then get the
