The whole earth is divided into twenty-four time zones, each time zone has its own local Time. For international radio communication, a unified TimeIs called Universal coordination Time (UTC, Universal Time Coordinated ).

For example, in my example, [01/Aug/2008: 14: 06: 30 + 0800] is a local Time(Beijing) Time)
UTC + time zone Difference = Local Time

The Time Zone difference is positive in the east and negative in the West. Here, the UTC + 8 Zone Time Zone difference is recorded as + 0800,

UTC + (+ 0800) = Local (Beijing) Time(1)

So, UTC = Local Time(Beijing Time)-0800 (2)

14:06:30-08:00:00 = 06:06:30 THIS IS UTC TimeBut sometimes you will get Time
This is also a problem...
