An overwhelming number of Sydney-siders are completely stumped about whether they lost or gained sleep when daylight savings ended this morning, a NASA study has revealed.

One Sydney man said he used the confusion to his advantage.

“Due to my phone’s clock changing automatically overnight, my body clock was confused, and I had no idea what time it ‘really’ was,” said the man. “I just told myself that 9am today time is probably more like 5pm or so yesterday time, so I took myself to the pub for a few schooners to help adjust.”

Other people chose to ignore the issue for now.

“Look, I’m not even going to worry about it today,” one woman said. “I’ll keep it up my sleeve and use daylight savings as an excuse to be four hours late to work on Tuesday.”

Daylight savings has been cited as the number-one reason for people waking up feeling horrible today, despite the fact that many have eaten nothing but pingers since knocking off work for the long weekend on Thursday afternoon.
