I was confused because the old wiki did not properly redirect me to the new page :
http://wiki.roblox.com/index.php?title=Os.time&redirect=no
https://developer.roblox.com/api-reference/lua-docs/os
This caused me to assume it wasn’t on the wiki (Foolishly I know, But I’m sure I’m not the only one who still attempts to find things by googling it followed by wiki)
