Hi,
A peculiar situation ( every time DST ends ): DST ( = UTC+1 ) ended, for example, in 1979 - in Portugal - the 30th September at 2 AM - it lasted until 1h59m59s AM and, one second later, corresponded automatically to 1 AM ( UTC 0 ). Ok, that's fair. But now, let's supose that we know of an event - of any kind, important or not - that ocurred at 1h30m AM in that day. Which system do we apply to know the exact UTC of the event?
It could have happened during DST, 30 minutes before the change of time - so, since DST was active, it would have happened at UTC 0h30m AM ; but it could have happened after the change, 30 minutes after DST ended - UTC 1h30 AM ( since the correction was made ). So, what will it be? Shall we throw a coin?
This time issues give me an headache...
Kind regards,
Kepler
