If the trip planner form on your website does not properly transmit to Google Maps the time and date of a planned trip, your trip planner form may be out of date.
In the current version Google Maps, previously-acceptable formats for "time" and "date" parameters (form inputs) are not used in the trip planning results. This screen recording shows the issue.
Request an updated trip planner form from Trillium to resolve this issue.
In the new version Google Maps, the "time" and "date" parameters (form inputs) need to be formatted thus,
date: MM/DD/YYYY ("7/24/2014")
time: HH:MM AM/PM ("1:30 PM")
The new trip planner form has been updated to format dates and times in this way. Old trip planner forms will need to be updated to format the date correctly.
