Update clock dependency

[Helkafen]

The data constructors can be useful for testing.

Packdeps found that clock 0.5.1 has been released, but utc.cabal requires the following bounds:

• clock >= 0.3 && < 1
• clock >= 0.3 && < 0.5

Is it ok to update it?

Hi,

I'm a little hesitant with the proposed change. The reason I hide the constructors is to make illegal state unrepresentable. If at all, one might consider to export them through an Unsafe or Internal module.

If

Prelude Data.UTC> addYears 25 epoch >>= addDays 23  :: Maybe Date
Just 1995-01-24

is too tedious to write for testing it might also be a solution to add an IsString instance for Date, Time and DateTime that fails with an error on invalid input.

P.S. Thanks for noting the clock update. I will merge that one in.

Yes that makes sense. Thanks for your insight.
