Reimplement Show and Read instances for TimeStamp

Refactor Read and Show instances. Solves bug of discarding nanosecond
precision. Implement `convertToTimeStamp` copying technique used in
implementation of `getPOSIXTime` from **base** Data.Time.Clock.POSIX.

Rename test case to _instance-test_ from InstanceTest.hs.

Update test with more comprehensive known examples.
