testWithEnvironmentEdge

public void testWithEnvironmentEdge()

In timezone GMT+08:00, the unix time of 2020-08-20 11:52:41 is 1597895561000 and the unix time of 2020-08-20 15:04:00 is 1597907081000, by calculating the delta time to get expected time in current timezone, then we can get special hour no matter which timezone it runs. In addition, we should consider the Daylight Saving Time. 1. If in DaylightTime, we need reduce one hour. 2. If in DaylightTime and timezone is "Antarctica/Troll", we need reduce two hours.
