HOL time

Hi, I wondered, what is the HOL time? What's the difference from GMT? I don't see it anywhere, only events like Quidditch are planned in HOL time. 
HOL time can be found on HOL's Calendar page, which is at this link.
It will always be the same as the time kept in the United Kingdom, which is GMT in the winter and BST (GMT + 1) in the summer. So you can think of "HOL time" as "London time", for example and it will always be right.
