Time travelling

There's something very fishy going on with our DAB radio. I went to check the time today to find its clock is nearly 80 years out. Reminds me of the worries about the Millennium Bug. Where I worked we did a dummy run a few weeks before by simply setting our computers to a minute to midnight on New Year's Eve. When they changed to the year 2000 without any of our systems falling over we knew it was going to be alright. Not so sure about going back to 1942......
