This article describes how to use the altzone () method to process time zones in Python. it is a basic knowledge in Python. if you need it, refer to the altzone () method as the attribute of the time module. The offset returned for the local DST time zone, in UTC West Second, if one is defined. This is a negative value if the local DST time zone is east of UTC (for example, Western Europe, including UK ). Only this is used. if the daytime is not zero.

The younger brother reinstalls the XP system at noon today, restarts it, enters grub, selects the XP system to enter, and then reports an error, prompting to press any key to continue. When the ENTER key is continuously typed, the error is repeated. Then I entered the linux system and succeeded in it. I have a classmate who

It then internally executes all the calculations described above and returns a string containing the local time of the city.Here are some samples of the output from List A.M
