Web Analytics & Daylight Savings Time

Much is being made about computers and switch this year to day light savings time happening two weeks earlier. Yes if you didn't download and install the appropriate patch, your personal computer will show the wrong time (off by an hour). So, what about your web analytics product?

As the clocks spring forward by an hour will you show an hour gap in your log reporting? The answer can be a bit complicated, but here goes the long and short of it.

If you're using a hosted web analytics tool like WebTrends OnDemand or Google Analytics, everything should be fine as I would expect these firms to have patched all their servers and planned for this change. If you're processing log files on your own server there are a couple of things to look out for.

First, is your web server or log data collection server patched and set to adjust automatically for the time change? If not, the entries in the log file will be off by an hour. Next, is your web analytics server and is it patched and ready for the time change. If either of these are not synchronized, then you'll have problems.

Just remember, the clocks are moving forward by one hour. So no matter what you do you'll see a gap as the clocks jump from 1:59:59 am to 3:00:00 am. The problem is if you don't see this event.

So plan and don't panic you still have a few days to prepare for it.
