Just a heads up that SMAPI removed Harmony 1.x support starting in 4.0.8 so this mod can't be used anymore. I haven't switched yet but a couple similar mods have been forked and updated, Pause Time in Multiplayer Revived (edit: tried this one but it doesn't work, known issue but the maker can't reproduce it oddly) and Time Master (UNOFFICIAL UPDATE). Make sure to read the readmes as there's plenty of things that might behave differently than you might expect.
