Hi, it's my job!
I have been doing Drupal work for a very long time. I can add this date field into getlocations field. It's possible with following information:
"Getlocations has the option to use the Infobubble and Markermanager or MarkerClustererPlus Javascript Libraries for Version 3 of Google maps. There are also options for how multiple markers are displayed and switches for TrafficLayer, BicyclingLayer, Panoramio, TransitLayer, WeatherLayer and Transit Points and Points of Interest styles. Administrators can add their own styles as well."
Please message me to get started right away.
My bio: I'm a Drupal themer/developer, I have over 6 years working on various Drupal projects from theming (Design, HTML, CSS, Javascript) to development (PHP, MYSQL, Drupal). I can create new themes, fix theme issues and module issues, create and upgrade Drupal sites, also suggest the best solution for Drupal site owners.
Thanks,
Hoa
