Get the time zone code

Sometimes you need to get to the current time zone in the project

Ten  - :notoginseng: + 0800

+800 means the current time zone is the East eight zone.

My idea is: Pick a point in time, which is 0 points in Greenwich, then the current number of hours in a global location is the number of time zones for that location. If the current time is greater than 12 points, it proves that the location is west of Greenwich.

The code is as follows:

#include <time.h>#include<stdio.h>#include<sys/time.h>intTime_zone () {time_t currtime=1420070400; structtm* PTM = localtime (&currtime); intCHR = ptm->Tm_hour; if(Chr > A) CHR-= - ; returnCHR;}intMainintargcChar*argv[]) {printf ("Time Zone is%d\n", Time_zone ()); return 0;}

In the native execution result:

Time Zone is 8

Korean Machine execution Results:

Time Zone is 9
