Hi all,

This proposal is to change directory to use the time package rather than the old-time package. This will hopefully be a significant step towards actually making the transition in general.

I'm not sure if POSIXTime or UTCTime is the better type to use. Does anyone know?

I started off with UTCTime, then switched to POSIXTime as UTCTime didn't have a Show instance. I've since found that actually UTCTime has both Show and Read instances, but they are orphaned. So actually, if UTCTime is the better type then switching back to UTCTime would allow us to fix this comment in hpc: -- We would rather use ClockTime in Mix, but ClockTime has no Read instance and simplify the code slightly.

Attached are patches for directory, hpc and ghc.

Suggested discussion period: Until 5th Nov 2011.

Thanks Ian +1. I'd like to transition to a single package as much as possible, and I think UTCTime is the right data type. +1 to transition to a single package. Perhaps this belongs in a separate discussion, but is there any plan to have time provide the locale stuff directly instead of our code needing to depend on old-locale? If I'm not mistaken, implementing such a strategy at the same time would mean that user code could then ignore two old-* packages. I agree, this is quite confusing to have to get things from a "old-" package in
