Time Interval Examples
In interval expressions, a positive or unmarked interval is based on the start
time, and a negative interval is based on the end time of a time expression.
For example, if the start time is y, the end time is t, and the interval is +5h
for a Sampled Data function, then interpolated values are generated at y,
y+5h, y+10h, y+15h, and y+20h. If the interval is -5h, the interpolated
values are generated at y+4h, y+9h, y+14h, y+19h and t.
