Inaccuracy in OneMap API documentation

The API documentation of the routing service states that the input format of the date should be:
The date of the selected start point in YYYY-MM-DD.
EG: 2016-04-30

However, in practice, the API actually accepts MM-DD-YYYY. Furthermore it silently fails, defaulting to the current date, which can be easily missed

Our routing team will relook at this issue.
