Can you have a close look at the actual and expected result? The DST change does make the 3rd role in the Actual result right. But it's the 4th role and 5 role which is not right, as I mentioned in the expected result. Time should not freeze for one hour after changed in DST. The DST website did not mention this rule at all. Here is the printout of the return of strtotime function. 1236493432 1236497032 1236500632 1236500632 //one hour lost. expected is 1236500632+ 3600 1236504232 //same here The absolute time value should not be affected by DST.
