So a post is first made at say 2.45am before the switch. Then another post is made 30 minutes later and and now shows 2.15am???
How do we timestamp anything that happens during that hour?

It's stored on the servers as GMT and your computer converts it to your current time.

This is actually closer to the correct answer. Most computer systems store time in seconds or milliseconds since epoch (usually 1 Jan 1970) and then the time get changed to your local timezone when displayed. On OzBargain, you can change the timezone in Locale settings.
@donamique — yes, the later post will appear to have a time earlier than the former.
Today on unsolved mysteries we explore what happens to Posts Made during The Overlapping Hour Switchover for Daylight Saving. Do these post really exists?
Inception.

I wish I could turn the clock back 20 years, not just 1 hour.
make sure you bring 20 years worth of winning lotto numbers with you… and do exactly as you did up until you're done winning the lotto
Shame the QLD border is closed, you could go back 50 years otherwise.

try Fyling back and forth between Samoa and American Samoa. You can have two Friday nights in a row.
Who's posting at 2:45am? ¯_(ツ)_/¯
Someone living in Perth perhaps?
Daily saving resets at the local regional time, so when Sydney is resetting clocks, Perth isn't for another 2 hours. But I guess, it comes down to the displayed posting time, which appears to be differential(that is the difference between the post being made and when you are online/reading) rather than reference based, eg GMT+.
Times would only appear to be doing something strange if someone in Perth was looking at a post from eastern states during the time you described. But again, who's posting at 2:45am? Drunk ordering online goods is another thing entirely.
Fully open to a technical correction by others with a better understanding/knowledge.From a technical point of view, times should be stored in UTC (rough equivalent of GMT). Once you have an absolute reference for time, any point of time can be translated to a given timezone. And yes, with that information 0245ADST is not same as 0245AEST.
@nahkk: So say I'm based in Sydney, all posts would have their time stamps wound back an hour after last night's adjustment? And then 6 months down the road round forward by an hour?
There would be people posting in Perth at 2:45am Sydney time? Also I was awake last night but not drunk, couldn't sleep.
Later posts become earlier posts, and earlier posts become later posts. That is they don't just disappear altogether.
They get merged with the Covid-19 megathread..
