Convert Timezone

The timestamp returned in OpenWeatherMap API is the time of the user's local system time.

Here are the steps to convert it to the query location's time:

1. Convert user's local timestamp to UTC timestamp

   import time
   '''convert user's local timestamp to UTC timestamp'''
   
   def get_location_timestamp():
    timestamp = data['dt']
    offset = time.altzone    #Get the offset of user's local DST timezone:
    utc_timestamp = timestamp + offset
   
    return utc_timestamp
   

2. Get the location's latitude, longtitude from OpenWeatherMap API

   location = '{:f}, {:f}'.format(coord['lat'], coord['lon'])
   

3. Access Google Timezone API, pass the location's latitude, longtitude, and the UTC timestamp, get the offset of query location's DST timezone

   https://maps.googleapis.com/maps/api/timezone/json?location={latitude, longtitude}&timestamp={timestamp}&&language=zh-CN&key={key}
   

   {
   "dstOffset" : 0,
   "rawOffset" : 28800,
   "status" : "OK",
   "timeZoneId" : "Asia/Shanghai",
   "timeZoneName" : "中国标准时间"
   }
   

4. Calculate the location's timestamp

location_timestamp = utc_timestamp + dstOffset + rawOffset

Get Weekday

from datetime import datetime
import calendar

dt = datetime.fromtimestamp(timestamp)
weekday = calendar.day_name[dt.weekday()]
weekday_abbr = calendar.day_abbr[dt.weekday()]
