Time on The Arc
by Lee Calcraft

Running Time opens a directory viewer containing three short Basic programs, Time-1, Time-2 and Time-3.

Time-1 displays the current date and time, read from the Basic pseudo-variable TIME$. The purpose of the program is to demonstrate how parts of the time and date can be extracted.

Time-2 advances the time by one hour, by reading the time from the Basic pseudo-variable TIME$, advancing it by one hour, then writing the result back into TIME$.

Time-3 sets the time back by one hour, by a similar method to Time-2.

Note that Time-2 and Time-3 only change the hour; they will not change the date if run within one hour of midnight. For this reason Time-2 should not be used between 11pm and midnight, and Time-3 should not be used between midnight and 1am.
