Efa should use utc

EFA does not use the correct TimeZone for requests.  
This is a problem for TFL: If you request a ride for "now", TFL will interprete it with the false timezone and return a ride for "an hour from now"

There's also an old Issue on [Google Code](https://code.google.com/p/public-transport-enabler/issues/detail?id=14)

An alternative could be to set `DATE_FORMAT.setTimeZone(timezone())` and  `TIME_FORMAT.setTimeZone(timezone())`
