Day Light Saving bug in Amazon Order Tracking

According to Wikipedia, Daylight saving time (DST) or summer time is the practice of advancing clocks during the lighter months so that evenings have more daylight and mornings have less. Typically clocks are adjusted forward one hour near the start of spring and are adjusted backward in the autumn.

And how many times we have seen that how this concept has created troubles for not only small software but also for giants. iOS for iPhone and iPad has already been culprit for having some nasty bugs related to this. And it was rumored that they have done the same mistake again in their latest iOS 7 as well.

Anyway, this post is not about Apple so let me come straight to what I found. I ordered a few books from Amazon UK around 10 days back and was expecting delivery anytime. When I checked the order status yesterday (29th March 2014), the status on the web site showed that the package is in transit (Amsterdam) and has been out for delivery on 29 March 2014 9:49:17.

That’s another story that I am still waiting for my package to me received. This triggered me to check the status again today (on 30th March 2014) and this is what I saw.


Basically, the same message but the time stamp was shifted 1 hour back. That is simply a programming error where they converted the time of out for delivery because of DST. But that’s not how it should be, at least in my opinion.

Not something which Amazon needs to take real action on but they might want to look at it.

And btw, @Amazon do I get a free gift card for finding this bug in your system? J
