Table Datetime conversions

[insomniacc]

I'm currently in two minds to implement this or not.
Currently dates/times are all considered strings, they are excluded from the get parameters, but can be used in query strings which expects the 'snow' datetime formats anyway.
Set command parameters also expect the snow format as a string.

It's possible to change the behaviour of the set commands and apply datetime conversions to the parameters so they can accept PowerShell standard datetimes but I'm not sure if I should leave this alone for consistency or implement for usability.

If once this is released I get any feedback I'll take another look.
