THIS IS NOT A DUPLICATE! PLEASE READ THE DESCRIPTION CAREFULLY.

When executing the following command:
/effect @p saturation 1

You receive this message:
Given (player) saturation for 1 second(s).

However, you only receive 1 tick of saturation. This is intended, but the message should say that you recieved 1 tick of saturation, instead of 1 second of saturation.
