Title: Removed mixture of UTC and Timezone-specific handling of timestamps

Timestamp handling contained mixture of UTC (in code, and cassandra default) and timezone-specific.
I replaced the datetime's now and fromtimestamp calls with utcnow and utcfromtimestamp.

This also solves the bug on issue #167
