timezone

问题 I have left my application.rb as it was and by default it is storing datetime in UTC. Now at the UI level (for displaying only) I want to convert the datetime to the user specific timezone. How can I convert the UTC datetime I get from postgresql and then convert it to the timezone that I will store for each user. I want to make this conversion using the Offset so like: -5:00 or +4:00 Is it ok to do this, because I was just checking some locations and it seems their offset changes during the

问题 I'm trying to write a world clock app that returns the sunrise and sunset information for a given time zone. The thinking is that the user will either specify the GMT offset or give the time zone explicitly. Then the application will look up the latitude and longitude using the java.util.TimeZone found (or possibly given the GMT offset). I realize the time zones are usually not a very accurate way to get geolocation information since they are mostly based on political borders, but it seems

问题 I'm a greenhand for strongloop. My datasources.json config is as follows: "platformDB": { "host": "localhost", "port": 3306, "database": "way", "username": "root", "password": "root", "name": "platformDB", "connector": "mysql" }, and UserAccount is my one model as follows: "name": "UserAccount", "plural": "user", "base": "PersistedModel", "idInjection": true, "properties": { "id": { "type": "number", "required": false }, "accountName": { "type": "string", "required": false }, "roleName": {

问题 I have a sql query to obtainrecords for a date range. My query works find byut when I analyzed data, I found that the records are retirved base don GMT timezone value, thus making the restults incorrect. I get my time from a unix epoch value in database. SELECT tableA.columnA,tableB.columnB FROM tableA INNER JOIN tableB ON tableA.aId = tableB.aId WHERE (to_date('1970-01-01 00:00:00 +10:00','yyyy-MM-dd hh24:mi:ss') + (tableB.epochValue/60/60/24/1000)) > to_date('--FROM_DATE--', 'yyyy-MM-dd

问题 I am creating a web application that will display the dates of various events that happened within the application (like a document being produced, for instance). Of course, the date displayed needs to be considerate of where the user is located (not just blindly output the stored date, since that would be the server local time). I've made a sample application that lists all the time zones, lets you choose one and then outputs some stored UTC dates in your selected time zone, adding an hour

问题 Was looking at this tutorial here http://pellepim.bitbucket.org/jstz/ on automatic timezone detection using javaScript which detects the device's time zone setting. I was wondering if anyone had any idea (ballpark is fine) of how accurate this method is of detecting timezones? Thanks for your time! 回答1: From the "limitations" section of the project page: This script does not do geo-location, nor does it care very much about historical time zones. So if you are unhappy with the time zone

问题 I use php's date_default_timezone_set() and set it according to user's timezone field in the the user table. So with ease I can show date/time to users and get date/time from them. But for storing date related values in database, I have to use the standard GMT timezone. The question: What is the best or maybe the standard way for switching to/from user_timezone and GMT? Do you suggest me to follow these steps when I want to insert or update a field in database? Change the timezone using date

问题 I want to parse a date into a javascript date object. I am using the following new Date(Date.parse('2012-08-01')) The problem is my input date can be in multiple formats and parsing it should always give me the date object with the date as 2012-08-01 00:00:00 in local timezone. What are possible options in javascript without using any third party libraries ? I have a possible solution. But my concern is should i be worried that this will not work in certain android/iphone/kindle/surface

问题 I am trying to get the local time in spark-scala but it is returning UTC. I am using java.time.LocalDateTime to get the current timestamp.

The current output is UTC. I need the
