Out of order blocks?

[Stevets]

Why do I sometimes see the age of older blocks being reported as newer than more recent blocks on blockchain.info?

For example blockchain.info shows that block 282438 is 25 minutes old and block 282437 is 18 minutes old. Wouldn't the higher numbered blocks always have a lesser number for age?

A timestamp is accepted as valid if it is greater than the median timestamp of previous 11 blocks, and less than the network-adjusted time + 2 hours.

So, the order is right. The site receive Block #282438 23 minutes after receiving Block #282437.
