Python datetime.utcoffset() 方法和示例

utcoffset()函数用于返回一个 timedelta 对象，该对象表示本地时间和 UTC 时间之间的差异。

• 该函数用于在 datetime 模块的 datetime 类中使用。
• 这里 utcoffset 的范围是“timedelta(hours=24) <= offset <= timedelta(hours=24)”。
• 如果偏移量在 UTC 以东，那么它被认为是正数，如果偏移量在 UTC 以西，那么它被认为是负数。由于一天有 24 小时，因此 -timedelta(24) 和 timedelta(24) 是可能的最大值。

Syntax: utcoffset()

Parameters: This function does not accept any parameter.

Return values: This function returns a timedelta object representing the difference between the local time and UTC time.

实施例1：在此输出是无因为现在（）函数返回的日期和时间UTC格式，因此本地时间，即之间的差，现在返回（）函数和UTC时间是没有的。

Python3

# Python3 code for getting
# the difference between the
# local time and UTC time
  
# Importing datetime and pytz module
from datetime import datetime
import pytz
  
# Calling the now() function to get
# current date and time
date_time = datetime.now()
  
# Calling the utcoffset() function
# over the above intitialized datetime
print(date_time.utcoffset())

输出：

None

示例 2：查找时间偏移量

# Python3 code for getting

# local time and UTC time
  
# Importing datetime and pytz module
from datetime import datetime
import pytz
  
# Calling the now() function to
# get current date and time
naive = datetime.now()
  
# adding a timezone
timezone = pytz.timezone("Asia/Kolkata")
aware1 = timezone.localize(naive)
  
# Calling the utcoffset() function
# over the above localized time
print("Time ahead of UTC by:", aware1.utcoffset())

输出：

Time ahead of UTC by: 5:30:00

# Calling the now() function to

timezone = pytz.timezone("Asia/Tokyo")
aware1 = timezone.localize(naive)
  
# Calling the utcoffset() function
# over the above localized time
print("Time ahead of UTC by:", aware1.utcoffset())

输出：

Time ahead of UTC by: 9:00:00
