They are used to determine when to switch to daylight savings time,
and how much to adjust the clock by, etc.  The standard USA zone is
compiled in, but if you need a different zone, you can set the TZ
environment variable to refer to those files (documentation needed).

This is required to convert the PC's "local time" to unix's concept of
"seconds since the Epoch".
