| Returns the date of the next roll point after the currentDateTime date passed to the method. |
| </p><p> |
| The basic strategy is to subtract the time parts that are less significant |
| than the rollpoint from the current time. This should roll the time back to |
| the start of the time window for the current rollpoint. Then we add 1 window |
| worth of time and get the start time of the next window for the rollpoint. |
