Background:: I'm living in US. But the there is a five hours difference between the Colab time (I specify the US timezone) and local time.

!date

结果:世界标准时间2019年8月7日星期三16:20:40

推荐答案

您可以分两个步骤更改时区:

You can change the timezone in two steps:

第1步:在层次结构中找到您的时区名称

Step 1: Find the name of your timezone in the hierarchy

!ls -al /usr/share/zoneinfo/

对于美国，您将通过以下方式再遍历时区树:

For US, you would then traverse the timezone tree one more level by:

!ls -al /usr/share/zoneinfo/US

这给你

drwxr-xr-x 21 root root 4096 Dec 22 02:14 ..

lrwxrwxrwx  1 root root   17 Oct 23 06:18 Samoa -> ../Pacific/Midway

第2步:

使用在步骤1中获得的正确参考设置时区.如果您住过在芝加哥，正确的参考是: Central .您可以通过以下方式更改Google Colabo时区:

Set the time zone with the correct reference obtained in Step 1. If you lived e.g. in Chicago, the correct reference would be: Central. You can change the Google Colabo timezone by:

!rm /etc/localtime
!ln -s /usr/share/zoneinfo/US/Central /etc/localtime
!date

请记住正确的参考是在两个层次的层次结构中，其中首先包含区域( US/Central )，而不仅仅是时区 Central .

Remember the correct reference is in a hierarchy of two levels containing the region first (US/Central), not just the time zone Central.
