Linux time and time zone (Memo)-Linux general technology-Linux programming and kernel information. The following is a detailed description. The first thing to note is that my system is fedora, and other systems may be different. 1. The time is

The tzset seems to be in effect only at the time of initialization, which is useless when tzset is called multiple times.Today a little in-depth search for the implementation of the Tzset in glibc, found that this is not the case, its real

All the while, Tzset seems to take effect only when it's initialized, and it doesn't work when Tzset calls multiple times. Today a little in-depth search of the glibc in the implementation of the Tzset, found that is not the case, its real

The first thing to say is that my system is fedora and other systems may not be exactly the same. 1, the time is kept in the hardware Real Time Clock (RTC), the RTC is powered by the motherboard battery, even if the power off source will not cause
