Question

我想将UTC时间转换为用户的浏览器时间。我尝试了一个厌恶，但它只显示我的系统时间。使用django应用程序。任何研究可以帮助我。

    import pytz
    from tzlocal import get_localzone
    def utc_to_local(utc_dt):#utc_dt that is UTC time
        local_tz = get_localzone()
        print local_tz #that is display system timezone inplace of USER's timezone

我尝试使用以下代码。

import time
from datetime import datetime
from dateutil import tz
utc = datetime.strptime(str(utc_dt)[:19], '%Y-%m-%d %H:%M:%S')
return time.mktime(utc_dt.timetuple()) * 1000

将utc时间转换为秒，然后使用javascript需要使其成为本地时间。但转换价值不准确，并显示错误的日期。

Javascript代码。

//1449206930000 #Seconds when above code run
//1449226703.79 #that is correct >> time.time() in python = 1449226703.79

#below code give perfact output
var date = new Date(parseInt(1449226703.79, 10) * 1000);
console.log(date);

#below code not working 
var date = new Date(parseInt(1449206930000, 10) * 1000);
console.log(date);

此致

您需要先找到用户时区，才能在当地时区转换时间。

有两种方法可以做到。

1）简单地传递UNIX时间戳然后使用Javascript在浏览器momentjs上以人类可读时间转换它可以帮助您。

function human_time(unixtime, tz) {
    var t=moment.unix(unixtime);
    return t.tz(tz).format('DD/MM/YY HH:mm:ss');
}

2）Use IP address or HTTP headers to detect the user location然后使用pytz转换您在用户系统时区中的时间，而不是您自己的django / server时区。

def get_user_timezone(request):
    return request.visitor.location.timezone

def human_time(dt, tz="Asia/Kolkata"):
    try:
        tz = pytz.timezone(tz)
    except:
        tz = pytz.timezone("Asia/Kolkata")
    dt = dt.astimezone(tz)
    return dt.strftime(r'%d/%m/%Y %H:%M:%S %Z')

 def view_get_local_time(request):
     tz = get_user_timezone(request) #detect user timezone, base on IP
     text = human_time(timezone.now(), tz) #convert server-time to detected timezone
     return HttpResponse(text)

注意：第一种方法是最优选的方法。
