Handling of UTCTime is confusing #31

Closed joehealy closed 6 years ago

joehealy commented 6 years ago

When using pretty-show v 1.6.16:

getCurrentTime >>= pPrint

2018 (-08) (-05) 06 : 49 : 43.285507738 UTC

The negative numbers are very confusing.

I gather from some of the early issues (#2 from memory) there is special handling for date types.

Thanks for point thins out. This is pretty tricky as there are all kinds of ways in which times could be printed, and they don't match the standard show conventions. Having said that, I made some changes that, I think, make the times in this format a little more readable:

getCurrentTime >>= \x -> pPrint [x,x]
[ (2018 - 08 - 05) (10 : 15 : 37.139576193) UTC
, (2018 - 08 - 05) (10 : 15 : 37.139576193) UTC
]

This should be available as version 1.8.1 on Hackage.
