Time in MM Info [patch]

Attached is a patch to support sending time to the device.

It adds two per-bts configuration elements: tzunits and tzdir.

tzunits are the number of units from GMT.  Each unit represents 15 minutes of time.

tzdir is the direction of the units from GMT.  tzdir 0 means GMT-tzunits and tzdir 1 means GMT+tzunits.

So for example, if you're GMT+1 you want: bts 0  type nanobts  band PCS1900  cell_identity 0  location_area_code 1  training_sequence_code 7  base_station_id_code 63  tzunits 4  tzdir 1  ms max power 15  cell reselection hysteresis 4
