[英]moment-timezone parsing the given time zone
I have an issue when parsing the Date object using the moment-timezone 使用moment-timezone解析Date对象时遇到问题
I am creating a nodejs app that should check the new Date() object with arbitrary time from database (and act accordingly). 我正在创建一个nodejs应用程序,该应用程序应该使用数据库中的任意时间检查新的Date()对象(并相应地执行)。 The time, and the timezone are persisted in database.
时间和时区保存在数据库中。
In example 在例子中
time | timezone
11:00| US/Eastern
When a REST call comes, I have to take new Date() object and to transform it to given timezone and see whether the current time is later than 9am. 当REST调用到来时,我必须获取新的Date()对象并将其转换为给定的时区,并查看当前时间是否晚于上午9点。 But servers timezone and persisted timezone are not the same.
但是服务器时区和持久时区并不相同。
I create todays date string like this 我像这样创建今天的日期字符串
function getTodaysDate() {
var today = new Date(),
dd = today.getDate(),
mm = today.getMonth()+1,
yyyy = today.getFullYear();
if(dd<10) {
dd='0'+dd
}
if(mm<10) {
mm='0'+mm
}
return yyyy +'-' + mm + '-' + dd;
}
And trying to create Timestamp object with moment-timezone 并尝试使用moment-timezone创建Timestamp对象
startTime = moment.tz(new Date(getTodaysDate() + ' ' + '11:00'), 'US/Eastern');
But the framework correctly takes the date and transforms it to US/Eastern time zone. 但框架正确地采用了日期并将其转换为美国/东部时区。
So when I print startTime.format(); 所以当我打印startTime.format();
I get 我明白了
2016-08-01T07:00:00-04:00
And I would like 而且我想
2016-08-01T11:00:00-04:00
So is there a way using moment-timezone package to set the Date and time and to just treat them as given timezone? 那么有没有办法使用moment-timezone包来设置日期和时间,并将它们视为给定的时区?
You don't need any of the Date
object manipulation. 您不需要任何
Date
对象操作。 In theory, you should just be able to do: 从理论上讲,你应该能够做到:
var zone = 'US/Eastern'
var time = '11:00'
var result = moment.tz(time, 'HH:mm', zone).format();
However, there's a known bug with this that uses the UTC current date instead of the time zone's current date. 但是,有一个已知的错误 ,它使用UTC当前日期而不是时区的当前日期。 Until it's fixed, you have to do this instead:
在它修复之前,你必须这样做:
var zone = 'US/Eastern'
var time = '11:00'
var s = moment.tz(zone).format('YYYY-MM-DD') + ' ' + time;
var m = moment.tz(s, zone);
var result = m.format();
(this assumes your input time
value is in HH:mm
format) (这假设您的输入
time
值为HH:mm
格式)
So the problem was that 所以问题是
startTime = moment.tz('here the date goes', 'US/Eastern');
Was either expecting ISO format or manually formatted (syntax of this was not known to me), or the Date() object. 是期望ISO格式还是手动格式化(我的语法不为我所知)或Date()对象。 I first tried with this
我第一次尝试这个
2016-08-01 11:00
Moment library complained (I will post the full error message when I come to office). 时刻图书馆抱怨(我上任时会发布完整的错误信息)。
Add T. 添加T.
startTime = moment.tz('2016-08-01T11:00', 'US/Eastern');
I hate timedate libraries and how we track of time. 我讨厌时间库和我们如何追踪时间。
