2018-9: Earlier, Later, or the Same?
The system function ⎕TS returns a 7-element integer vector timestamp representing the current year, month, day, hour, minute, second, and millisecond in that order.
Write an APL function that given left and right arguments of such timestamps returns a ¯1, 1, or 0 if the left argument represents a time that is respectively, earlier than, later than, or simultaneous with the right argument.
Examples:
2018 4 1 12 34 56 789 (your_function) 2018 4 1 16 45 12 800
¯1
2018 4 1 12 34 56 789 (your_function) 2018 4 1 12 34 56 789

2018 4 1 12 34 56 789 (your_function) 2017 4 1 12 34 56 789
