A few posts back there's a little tip about calculating the difference between two dates by
calculating the timestamps for each and then dividing the difference by the number of seconds in one
day (86,000 or so).
However, as I found out, if you're living in a country that uses daylight saving time come
winter, then between certain dates you're gonna gain an hour/lose an hour, which might cause
unexpected results. In my case I was rounding up the number of days (it was to do with rental
periods) and what appeared to be exactly one day (12:00 one day to 12:00 the next) actually
calculated as 2. Clever ol' PHP. Stoopid ol' me ;-)
