Time in TBH

[K. Ryan]

I'm looking forward to starting a Tales of Blades  and  Heroes  campaign but I'm confused about something. There's a few references to things like poisons taking effect after a certain time but I can't find any reference to how long an initiative round is. In other words, how much time passes in 1 round in which everyone acts once based on their initiative? 
Thanks

It looks like the developers do not check this for me anymore which is a shame because I think this is my favorite game
