date-fns

问题 I am using date-fns to format dates If I pass a date that ends in Z, it knows that it is UTC, and I can format(date, "yyyy-MM-dd") and it will be in local computer time. If the date I want to express in local computer time is originally CST, is there something to add at the end instead of the Z, that will be understood by the format function as a CST date? Sorry if this is a bad question Edit: is there a way to do zonedTimeToUtc(myDate, 'UTC-6') in date-fns? (instead of using a time zone name

问题 const dt = new Date('2017-12-12'); console.log(format(dt, 'YYYY-MM-DD')); The above code logs 2017-12-11 in the US, but 2017-12-12 in India. I followed this github thread here and tried out things but am not getting the desired results. My expectation is to print the same date irrespective of time zone Why I need this : Consider a scenario involving birthdates. If i am giving some input date, it has to be displayed as same date in all regions irrespective of their timezones. 回答1: You will

问题 The displayed date in Material UI Pickers is 1 day behind the selected date: I selected 25th, the value in formik is 25th but the value displayed on the form is 24th. "@date-io/date-fns": "^1.3.13", "date-fns": "^2.9.0", import DateFnsUtils from '@date-io/date-fns'; import { MuiPickersUtilsProvider, DatePicker } from '@material-ui/pickers'; import { format, addDays } from 'date-fns'; <MuiPickersUtilsProvider utils={DateFnsUtils}> <FastField as={DatePicker} variant="inline" disableToolbar name

问题 I'm using date-fns to return some values as shown below: import { format, formatDistance } from "date-fns"; var date = new Date("2019-03-06 00:00:00"); console.log(format(new Date(date), "dd MMM, y")); It works fine on Chrome and returns We Mar, y But returns Invalid Date in Safari. I believe it's because the date ("2019-03-06 00:00:00") is not in ISO 8601 format. But this is the format I'm receiving from an endpoint. Is there any option to convert this to the right format and make it work on

问题 Problem It looks like when I use the format() function, it automatically convert the original UTC time into my timezone (UTC+8). I have been digging through their docs for hours and couldn't seem to find a way to default it to UTC time. import { parseISO, format } from "date-fns"; const time = "2019-10-25T08:10:00Z"; const parsedTime = parseISO(time); console.log(parsedTime); // 2019-10-25T08:10:00.000Z const formattedTime = format(parsedTime, "yyyy-MM-dd kk:mm:ss"); console.log(formattedTime

问题 I have a problem with my application. I have a website. I use date-fns to show a formatted date based on the user language. It works great, but I have updated date-fns and since then I have a warning. In my JavaScript code I use: const locale = require(`date-fns/locale/${props.match.params.lang}`) And with this, I can generate the right format like this: format(new Date(), 'D MMMM YYYY', { locale }) It works, but I dislike this warning I get when webpack is building. Can you help me to

问题 Is there a way to format/output a date in a specified timezone with the date-fns library?

问题 I'm trying out date-fns v2. I want to format a date in a string by using the toDate and format functions: import { format, toDate } from 'date-fns' format(toDate('2019-02-11T14:00:00'), 'MM/dd/yyyy') But get the following error: RangeError: Invalid time value 回答1: It seems that you are using Version 2.0 of date-fns, which is still in alpha (development) status currently. What functions are available and how they work still seems to change frequently. For example, while in version v2.0.0-alpha
