Examples\r\n       1    To change the TZ environment variable while running the date\r\n            command, type:\r\n\r\n            TZ=MST7MDT date\r\n\r\n            OR\r\n\r\n            env TZ=MST7MDT date\r\n\r\n            Each of these commands displays the time in mountain time and the\r\n            current date. The two commands shown are equivalent. When the date\r\n            command is finished, the previous value of the TZ environment\r\n            variable takes effect again.
