Question

below is the Scenario:

 1. (Host-machine)User will create tasks on the server by sending task information to the rest services of server (task_name,task_owner etc)
 2. (server-machine)server will receive information from the user and creates a timestamp(2017-08-07 08:42:07-04:00) along with timezone for the task and saves into a database
 3. user will do list tasks and user must be able to see task_name,task_owner and task_creation time

Assuming Host-machine and server-machine are on different timezones.

when user does list tasks we trigger the rest-services and processes the tasks timestamps and show local timestamps equivalent to server timezone.

 so,

    input: 2017-08-07 08:42:07-04:00
    output : 2017-08-07 17:30:03
    explanation: its converting from time stamp of one time zone to                              
                 another timezone.EDT is 2017-08-07 08:42:07-04:00 
                 IST is 2017-08-07 08:42:07+5:30 .
                 so, assume Local is IST the time must be ~17:30 
                 (8:42:07+9:30)

Answer 1

我认为Arrow会帮助您简化您尝试做的事情。服务器上的所有日期和时间都应该是UTC，并为每个用户保存正确的时区。使用arrow，您只需使用：

import arrow

time = arrow.get(input_time, 'YYYY-MM-DD HH:mm:ssZZ')

print time.to('local')

Answer 2

fixed this using the package called **tzlocal**



     def convert_date_format(self, server_time):
                local_date =parse(server_time).astimezone(get_localzone())
                return str(local_date.replace(microsecond=0, tzinfo=None))

 **explanation**

input:  "2017-08-08 15:35:27-4:00"

   1.function takes server_time as input converts to datetime object using 
    parse()           
   2.get_localzone() will fetch the local time zone                                   
   3.using the astimezone() converted the server_time to local timestamp     
   4.removed the microseconds and timezone fields

从服务器时间戳获取本地时间戳
