Time filters treated as text

[aditisg17]

A filter on time in API calls gives wrong result, as the resultant query takes time as "text" instead of "date"

API Call :
http://localhost:8080/SensorThingsService/v1.0/HistoricalLocations?$filter=(time ge '2017-05-19T10:10:27' and time le '2017-05-19T10:10:28')

Resultant PostgreSQL query:
select "e1"."ID", "e1"."ID", "e1"."TIME", "e1"."THING_ID"
from "HIST_LOCATIONS" "e1"
where "e1"."TIME"::text >= ? and "e1"."TIME"::text <= ?
order by "e1"."ID" asc

Dates in the URL must not be quoted as strings. If you quote them as string, they will be treated as strings.

v1.0/HistoricalLocations?$filter=(time ge 2017-05-19T10:10:27Z and time le 2017-05-19T10:10:28Z)

Don't forget to add the timezone and urlencode!
