In Orlando, when setting your user-specific date/time preference to "Both", you are unable to load Service Maps.
Steps to Reproduce
On an Orlando instance
Imperesonate a User, and change their date/time preference to "Both": System Settings (Cog) -> General -> Date/Time = Both
Load an Application Service map.
Expected behaviour: The map displays with all nodes and relationships
Uncaught TypeError: Cannot read property 'dateBoth' of undefined
