What time do the updates come out? (Hitman (2016))

that's how long I've been playing, I've never wondered how much updates come out, for
example, I could play in Sapienza only in the evening after the release,
and as if the question arises about the release of elusive goals, when it will be possible to play in them and those 48 hours that are given to them , from what moment will be counted,
maybe someone knows what time zone the updates are coming out or I'm not catching up with something ...
thanks)
