Units, times and trains….

When working on programs such as iCalMaker (iCal calendar editing software), and PhotoGPSEditor (geotagging photos with latitude and longitude coordinates) you become acutely aware of time and time zones. Working on chemCal (a chemistry concentrations and dilutions calculator for the iPhone/iPod Touch) makes you aware of units… so to be confronted by the following screen when buying a Newcastle to Glasgow train ticket is very confusing

So, what does this screen show?

What time is this?

Basically it is telling me, as train times given using a 24 hour clock, that the peak time for traveling from Newcastle to Glasgow is 01:15 to 04:00. As far as I know there are no trains going to Glasgow at that hour in the morning….

This just goes to highlight the importance of stating time, and getting the units right.

Yours, a very confused train passenger…..
