Working with timezones

Hi there, 

I am looking to set up a campaign that be run manually daily day at around 8am-10am (depending on internal readiness). We want this campaign to be received in users local time zone at the same time. Eg. Campaign run at 8am Melbourne time and received in New York at 8am (14hours later) 

I have been looking at the recommended set up as per documentation (see below), however not sure if this would work for us. The reason for this is that we then want to a new version of this campaign the day after with updated content. Based on the below this may not work due to the 24hr of eligibility. 

 I also looked at the option of running this as canvas and create separate audience paths and delays. However, can't figure out the best way forward. 

Can someone please advise on the best way approach?
