Golang Getenverror Examples

Example #1

File: zoneinfo_unix.go Project: WXB506/golang

func setupZone() {
	// consult $TZ to find the time zone to use.
	// no $TZ means use the system default /etc/localtime.
	// $TZ="" means use UTC.
	// $TZ="foo" means use /usr/share/zoneinfo/foo.
	// Many systems use /usr/share/zoneinfo, Solaris 2 has
	// /usr/share/lib/zoneinfo, IRIX 6 has /usr/lib/locale/TZ.
	zoneDirs := []string{"/usr/share/zoneinfo/",
		"/usr/share/lib/zoneinfo/",
		"/usr/lib/locale/TZ/"}

	tz, err := os.Getenverror("TZ")
