[英]Convert Epoch time to human readable with specific timezone
To convert epoch dateTime to human readable , using a simple new date(1495159447834)
will suffice.要将 epoch dateTime 转换为人类可读的,使用一个简单的
new date(1495159447834)
就足够了。
The problem I'm encountering now is that for my hybrid application, if the user set the time-zone in his phone date time setting to lets say GMT +12:00 ,the human readable dateTime will be different from what I would want the user to have and I would want him/her to follow the server timezone.我现在遇到的问题是,对于我的混合应用程序,如果用户在他的手机日期时间设置中将时区设置为 GMT +12:00 ,那么人类可读的 dateTime 将与我想要的不同用户拥有,我希望他/她遵循服务器时区。
Thus , how would I convert the epoch number to a specific given timezone in a human readable format.因此,我将如何以人类可读的格式将纪元数转换为特定的给定时区。
I have tried example like:我试过这样的例子:
var test= new Date('1495159447834 GMT+0800').toString();
and it returns me an Invalid Date.它返回一个无效日期。
If possible, I would want this without any libraries.如果可能,我希望没有任何库。 I have looked through the answers here and I believe that I could not find any answers I'm looking for.
我已经浏览了这里的答案,我相信我找不到任何我正在寻找的答案。 If there is any previously answered question with the same topic, do let me know and I will close this question!
如果以前有任何与同一主题有关的问题,请告诉我,我将关闭此问题!
You can use offset to convert your current datetime to a specific timezone.您可以使用偏移量将当前日期时间转换为特定时区。
function convertEpochToSpecificTimezone(timeEpoch, offset){
var d = new Date(timeEpoch);
var utc = d.getTime() + (d.getTimezoneOffset() * 60000); //This converts to UTC 00:00
var nd = new Date(utc + (3600000*offset));
return nd.toLocaleString();
}
// convertEpochToSpecificTimezone(1495159447834, +3)
The offset will be your specific timezone.偏移量将是您的特定时区。 Example: GMT +03:00, your offset is +3.
示例:GMT +03:00,您的偏移量为 +3。 If GMT -10:00, offset is -10
如果 GMT -10:00,偏移量为 -10
there are number of ways to convert between Epoch and Human readable format有多种方法可以在 Epoch 和人类可读格式之间进行转换
//Convert epoch to human readable date
var myDate = new Date( 1533132667*1000);
document.write(myDate.toGMTString()+"<hr>"+myDate.toLocaleString());
//this will return Wed, 01 Aug 2018 14:11:07 GMT //这将返回格林威治标准时间 2018 年 8 月 1 日星期三 14:11:07
//Convert human readable dates to epoch
var myDate = new Date("Wed Aug 01 2018 14:11:07 GMT");
var myEpoch = myDate.getTime()/1000.0;
// this will return 1533132667 // 这将返回 1533132667

set the initial date to the epoch and add UTC units.将初始日期设置为纪元并添加 UTC 单位。 Say you have a UTC epoch var stored in seconds.
假设您有一个以秒为单位存储的 UTC 纪元变量。 How about 1234567890. To convert that to a proper date in the local time zone:
1234567890 怎么样。要将其转换为本地时区中的正确日期:
var utcSeconds = 1234567890;
var d = new Date(0); // The 0 there is the key, which sets the date to
the epoch
d.setUTCSeconds(utcSeconds);
Or you can use momentjs或者你可以使用momentjs
moment.unix(yourUnixEpochTime).format('dddd, MMMM Do, YYYY h:mm:ss A')
or you can use this way或者你可以用这种方式
var dateVal ="/Date(1342709595000)/"; var date = new Date(parseFloat(dateVal.substr(6))); document.write( (date.getMonth() + 1) + "/" + date.getDate() + "/" + date.getFullYear() + " " + date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds() );
This is old, but I did it this way:这是旧的,但我是这样做的:
function formatDate(date, includeTime) {
const dateTimeFormat = new Intl.DateTimeFormat('en-US', {
year: 'numeric',
month: 'short',
day: 'numeric',
hour: 'numeric',
minute: 'numeric',
timeZone: 'America/Los_Angeles',
timeZoneName: 'short',
});
const [
{ value: month },
,
{ value: day },
,
{ value: year },
,
{ value: hour },
,
{ value: minute },
,
{ value: dayPeriod },
,
{ value: timeZoneName },
] = dateTimeFormat.formatToParts(date);
if (includeTime) {
return `${day} ${month} ${year} • ${hour}:${minute}${dayPeriod.toLowerCase()} ${timeZoneName}`;
}
return `${day} ${month} ${year}`;
This will output the time of the given timezone.这将输出给定时区的时间。
For example, if I have an epoch time (unix timestamp) and if I'm in Argentina, the time should be displayed as 03:45 GMT -3 of June 2, but with this code, it will be displayed as the time that should be displayed for Los Angeles.例如,如果我有一个纪元时间(unix 时间戳)并且我在阿根廷,那么时间应该显示为 6 月 2 日的 03:45 GMT -3,但是使用此代码,它将显示为应显示为洛杉矶。 My requirement was to display time in Los Angeles timezone, even if I visit the page from Argentina.
我的要求是在洛杉矶时区显示时间,即使我从阿根廷访问该页面。
