timezone

问题 I am trying to convert timestamp in to various time zone's local time and found certain TimeZone are not supporting in Chrome (v76.0.38) but working fine in Mozilla (v68.0.2). let d = new Date(1567083463); let n = d.toLocaleString('en-GB', { timeZone: "US/Arizona" }); Uncaught RangeError: Invalid time zone specified: US/Arizona at Date.toLocaleString () Several other timezones are also throwing the same error US/Alaska US/Mountain US/Central US/East-Indiana These timezones are officially

问题 Working with Node, moment.js and PostgreSQL 9.6 It's 2020-01-24 00:00:00+00:00 and Client A (the writer) is at offset -06:00 and casually INSERT s a record with a date field in it, with value 2020-01-23 , and thinks Well, this record will hold everything I need to store for date 2020-1-23 (their 2020-01-23 ) Now it's 2020-01-24 00:20:00+00:00 and Client B (the reader) is at offset +11:00 and wants to see the information (from the same db and table) regarding 2020-01-24 , BUT THERE IS NONE!!

问题 I have a strange problem in json date parsing. I am using the following to parse the json date: dateFormat(new Date(parseInt(user.RegDate.substr(6))), "mm/dd/yyyy") When my local machine (Client) is in different timezone from the server timezone, then it returns different dates when i try to retrieve the registered date of the users. For ex.: Registered date in SQL: 2010-07-22 19:00:00.000 When i debug in local machine which is in IST Timezone, the dates from JsonResult returned are: /Date

问题 Task to solve: Given a DateTimeOffset , its value has a particular Offset. I would like to serialize it with the exact form as it was represented, with that exact date and time value and exact same Offset value Problem Currently when serializing the moment is correct, but the formatted serialized version of the point in time is converted to the offset which is according to the current timezone. (This way although the point in time remains correct, but the original offset information lost)

问题 With this query: select sysdate from dual; the result is: 27-09-2018 07:50:50 -- this UK time with : Select dbtimezone from dual; output: +10:00 I want the sysdate to be of the same timezone of dbtimezone I was trying to do it with alter database set time_zone='AEST' , but i'm bit confused if this is the right solution.

问题 I have this below functionin my webapp to check if from OPEN to CLOSE time has elapse using a country timezone and it's working fine. Am trying to optimize my website, so my question is how can i make a function like this in javascript without the use of moment timezone? The moment timezone file is large and this is the only usage of it on my website. function isOpen(openTime, closeTime, timezone) { // handle special case if (openTime === "24HR") { return "open"; } // get the current date and

问题 I've found that toLocaleString can be effective in translating the time to a different timezone, as discussed on this question already. For example, to print the time in New York: console.log(new Date().toLocaleString("en-US", {timeZone: "America/New_York"})) "5/26/2020, 1:27:13 PM" That's great; this code gives me what time it is in New York, but only in string format. If I want to do something programmatic based on the hours, I'll have to parse that string. Is there a way I can generate a

问题 I've created a tool in JavaScript that determines the current UTC time and checks if another predetermined date has passed yet. I'd like to change my browser to another timezone and see if the tests still pass but I'm having trouble finding a way to do this. Is there a way to do this in Chrome dev tools? If not, do any other suggestions come to mind? 回答1: To do this in Chrome Dev tools you can use the Geolocation sensor emulation. Go to the 3 dotted menu, More Tools and Sensors. There's a
