Implement Relative Position Operators for Time Types

[chaitan94]

• <<: Is the first numeric or range value strictly left of the second one? • >>: Is the first numeric or range value strictly right of the second one? • &<: Is the first numeric or range value not to the right of the second one? • &>: Is the first numeric or range value not to the left of the second one? • -|-: Is the first numeric or range value adjacent to the second one? • <<#: Is the first time value strictly before the second one? • #>>: Is the first time value strictly after the second one? • &<#: Is the first time value not after the second one? • #&>: Is the first time value not before the second one?

Invalid operations should throw accordingly
