increase time range for timestamp by using specified granularity

Browse source 
previously we allowed users to specify a granularity for timestamp
e.g. seconds, milli, micro, nano
however we converted everything to nano before we stored it.
This reduced the allowed range for all time units to what
was allowed by timestamp. For example, with second granularity
you can represent billions of years within the capacity of
int64 but with nano its somewhere b/w 100-200 years.

So now, for timeunits of seconds, milli, and micro the range
is year 0001 - 9999. These limits come from what Go
supports.

So this uses unit specific function to translate
timestamps to values and vice versa to increase
the time range.
