[BUG] Correctly parse observedTimestamp

- Using the DateTimeUtility to parse the passed OffsetDateTime and using
  it for conversion to string
- Moving to actual src/main/java from test side as it is to be used in
  the prod code as well and only keeping the methods in use.
- Added test to fix the coverage issue
