[TYPO3-english] Naming convention of record icons with hidden, start-/endtime status

[Lee Perry]

Thanx Peter, this extension displays a similar table (Table Icon 
Listing) to my result table below :).

Okay, that means I'm on the right way - but can anybody explain the naming?
Why "__t", "__f" AND "__tf"?
Does "__t" stands for "To" and "__f" for "From" and not for "True" and 
"False"? But why "__tf" - does it stands for "To - From", but than "From 
To" would the better solution and in this extdeveval-extension I have to 
click the option "Starttime" to see the "__t"-icon and "Endtime" to see 
the "__f"-icon - very confusing, again!

Any clue?
