总之,结构体timezone在Linux系统中起着重要的作用,能够方便地处理不同时区的时间信息,为跨时区的软件开发和系统管理提供了便利。开发者在使用Linux系统开发程序时,可以充分利用结构体timezone的功能,来更好地处理时间和日期信息。
#endif 函数定义:time_t time(time_t* lpt); 如:time_t time = time(NULL); 2、struct timeb 结构:它有两个主要成员,一个是秒,另一个是毫秒;精确度:毫秒(10E-3秒); 由函数ftime()获取struct timeb结构的时间;其定义如下: struct timeb { time_t time; unsigned short millitm; short timezone;...

Provides information about a specific time change, such as the change from daylight saving time to standard time or vice versa, in a particular time zone.
Linux is removing support for the system call settimeofday from new architectures. The clock_settime system call does not support the struct timezone * argument. As a result, the glibc implementation of settimeofday will fail if a non-ze...
