Auto Entry 24–hour
This mode is used to automatically
enter time in a 24–hour format. It will
display a 00:00:00 without the HR MIN SEC
identifiers when the calculator is in a
cleared state. Time in this mode is
entered in the same way it is in the
H:M:S mode, but the time values will
roll back to zero or 00:00:00 after every
24 hours.
