Please describe the problem.

Building git-annex with GHC 9.14/time 1.15 fails with error "Ambiguous occurrence ‘Seconds’." in

  • Annex/StallDetection.hs,
  • Assistant/Threads/Committer.hs,
  • Assistant/Threads/Cronner.hs,
  • Assistant/Threads/Exporter.hs
  • Assistant/Threads/Watcher.hs
  • Command/FuzzTest.hs

time 1.15 adds "Seconds" to Data.Time.Clock, leading to ambiguity. Easiest fix would probably be to hide the export, alternatively use qualified import.

What steps will reproduce the problem?

Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
