Map: timeslider arrows layout with short variable name

[bobular]

My UD has a short "date" variable name

Needs to be

add margin-left/right: auto to div containing the date range selector

[bobular]

Maybe the arrows should be snug with the date picker inputs.

The arrows can have margin-left: auto and margin-right: auto respectively.
