Title: Invalid Activity appointment time with non-integer offset time zones (eg. GMT+6.30)

How to reproduce:
* in settings, set current time zone to GMT+6.30 (Rangoon)
* create a new Activity with appointment time 10:00 to 12:00 ; save
* in Activity details, the appointment time displayed is 10:30 to 12:30

The code assumed incorrectly that time zone offsets are always integers.
This changeset fixes it.
