问题 I have an int 1446159600 which is UTC/GMT date Thu, 29 Oct 2015 23:00:00 GMT. I tried to do conversion to the actual UTC date, but couldn't get it to work with Calendar, SimpleDateFormat, and Timezone classes. Can someone help me? 回答1: // print the time in local time zone Date date = new Date(1446159600); System.out.println(date); // print UTC time TimeZone utcTimeZone = TimeZone.getTimeZone("UTC"); Calendar calendar = Calendar.getInstance(utcTimeZone); SimpleDateFormat simpleDateFormat = new

问题 I am using <s:date> tag of struts2. To convert a date stored 04/09/2014 11:40:17 in UTC time to IST time I used struts2 date tag as belows : <s:date name = "dateregistered" format = "MM/dd/yyyy HH:mm:ss a" timezone = "GMT+5.30" /> and it always give me the date: 04/09/2014 06:10:17 AM .

Need to display local times over DST transitions using Javascript Date Object

烂漫一生 提交于 2019-12-22 05:25:07
问题 I am trying to output a series of times in hour (on the hour) intervals within Javascript (so inside a web browser such as Firefox). This series of times will overlap the short day (losing an hour in spring) and long day (gaining an hour in autumn). The output I'm looking for is in local time, i.e. with timezone and DST offsets applied. So for example, in the UK we have a missing hour from 01:00 to 01:59 on the short day such that the output would be: 00:00, 02:00, 03:00 And on the long day

Node JS current DST rules

老子叫甜甜 提交于 2019-12-22 05:11:31
问题 According to specifications, Node JS (ES5) should use current dts rules when working with Date objects. Current means "for now", not for a particular date. That's not perfect, but enough for me at this moment. Currently that rules are wrong (due to law changes in Chile). Simple probe: console.log(new Date()) Mon Apr 08 2019 12:48:08 GMT-0300 (Chile Summer Time) {} shows "(Chile Summer Time)" at the end of the default toString for a date. Actually we are not in Summer Time (it ended two days

UTC vs. GMT - Java vs. .Net

问题 In .Net UTC and GMT are not the same Difference between UTC and GMT Standard Time in .NET Is it the same with Java? Does Java has the notion that GMT has DST changes while UTC doesnt? Thanks! 回答1: Daylight Saving Time and GMT is different. GMT is GMT, wherever and whenever. GMT+0 is standard British Time GMT+1 is BST (British Summer Time) 回答2: As the documentation explains, GMT is equivalent to UT and the difference between UT and UTC is "is an invisibly fine hair to split".

Sequelize reads datetime in UTC only

谁说胖子不能爱 提交于 2019-12-21 21:35:55
问题 I have set the timezone option to my timezone ( Europe/Zagreb and I've tried with +01:00 too), and the time is saved as it should be, however, when reading the time from the database, Sequelize converts it to UTC. I have tried different timezones too, each is saved correctly, but always converted to UTC when read from database. Am I doing something wrong or is this a known issue and are there any workarounds? I create a new connection with: sequelize = new Sequelize(config.database, config
