Valve Time 

A Unit of time measurement similar to normal time, however very flexible - something that Valve says might take a week could take a day, or something that they say might take a month, will take a year. Generally fluid.

Team fortress 2 players got the bad end of Valve Time when the pyro update was first announced, and got the good end of it when they fixed the infinite health glitch in record time after it was found.

Valve Time 

The expanded time Valve uses when talking about anything that will involve them working. Like a new york minute, but in reverse. See Valve week and Valve month.

The conversion factor is approximately 2-6 times whatever the stated interval is.

Loose example of Valve Time from the Steam August 26 update news:

"Fans will remember that Blue Shift included a "High Definition Pack," a set of visually enhanced player and weapon models. We've had to iron out some technical wrinkles with how we deliver the HD Pack, but it will be made available through Steam within the next week or so."

As of November 20, 2005, this content still hasn't been released.
