[英]how to import an UTC timestamp to Luxon as it is? (Migrating from Moment)
I have this line in my app:我的应用程序中有这一行:
const createdOn: moment.Moment = moment.utc(created_on)
created_on
comes from an api endpoint like in this format: created_on
来自一个像这种格式的 api 端点:
{
...,
created_on: "2019-03-08T15:32:26.285Z",
}
This basically imports created_on
as an UTC timezone.这基本上将
created_on
导入为 UTC 时区。 created_on
is also UTC
. created_on
也是UTC
。 So, this method does not break the timezone and import UTC properly.因此,此方法不会破坏时区并正确导入 UTC。 Also I have this one:
我也有这个:
That generates current timestamp in UTC timezone.这会在 UTC 时区生成当前时间戳。
moment.utc()
Note that , If I just import date to moment and then convert it to UTC, my time goes wrong.请注意,如果我只是将日期导入到时刻,然后将其转换为 UTC,我的时间就会出错。 Moment by default assumes given date is equal to current visitors timezone.
默认情况下,Moment 假定给定日期等于当前访问者时区。 I need to import time as it is.
我需要按原样导入时间。 Which is UTC all the time.
这一直是UTC。
What is the equivelant on Luxon
? Luxon 的
Luxon
什么?
You can use DateTime.utc
and you can have a look at For Moment users section of Luxon's manual.您可以使用
DateTime.utc
,也可以查看 Luxon 手册的For Moment users部分。
You can find in theCreation section:您可以在创建部分找到:
Operation | Moment | Luxon | Notes ------------------------------------------------------------------------------------ From UTC civil time | moment.utc(Array) | DateTime.utc(Number...) | Moment also uses moment.utc() to take other arguments. In Luxon, use the appropriate method and pass in the { zone: 'utc'} option
So, if your input is a string, you can use from
method (like fromISO
) using {zone: 'utc'}
option因此,如果您的输入是字符串,则可以使用
{zone: 'utc'}
选项使用from
方法(如fromISO
)
Here a live sample:这是一个实时示例:
const DateTime = luxon.DateTime; const nowLuxon = DateTime.utc(); console.log(nowLuxon.toISO(), nowLuxon.toMillis()); const nowMoment = moment.utc(); console.log(nowMoment.format(), nowLuxon.valueOf()); const created_on = "2019-03-08T15:32:26.285Z"; const createdOnLuxon = DateTime.fromISO(created_on, { zone: 'utc'}); console.log(createdOnLuxon.toISO(), createdOnLuxon.toMillis()); const createdOnMoment = moment.utc(created_on); console.log(createdOnMoment.format(), createdOnMoment.valueOf());
