To do the project encounter the problem of the pit, need to get time zone in accordance with the timeline of the axis. For this search for a long time on the internet there is no JS code description to this aspect, finally I turned the next high school geography to write a function out.
This figure shows that the world is divided into 0 time zones, things 1-11 zones, and 12th time zones. Here's what I wrote about JS's function based on time zone output:
<!

The GetTime function is used here to get the time difference from midnight January 1, 1970 to the present, to match the difference between the current local and GMT time to obtain the GMT standard value. That is, the utctime variable inside the function.
Finally, a result diagram is attached:
