I know it refers to the time counting down....however, what does the T actually stand for?

This is all I could find...
"countdown is the backward counting to indicate the seconds, days, etc. remaining before an event occurs or a deadline expires. Typical events for which a countdown is used include the launch of a rocket or spacecraft, the explosion of a bomb, the start of a race, or the New Year.
In the context of a rocket launch, the "T minus Time" is the time before launch, e.g. "The countdown was held at T minus 5 minutes for 3 minutes and 40 seconds". The last ten seconds are usually counted down aloud "10, 9, 8, 7, 6, 5, 4, 3, 2, 1, Lift off!" "

T is time.
For the launch of the space shuttle, for example, T minus 10 minutes would mean 10 minutes before scheduled launch, and T plus 10 minutes would be 10 minutes after scheduled/actual launch.
T is used widely in engineering and physics as a reference, but scientists normally say T0, T1, etc.

T means "time"
e.g time minus 4 minutes
this means you only have 5 minutes time is equals to 1 min then 4 minutes remaining

Time. As in time for launch, time to go, time to take off.

"time" ... specifically "t0", which is the convention used to mark "began at ..."
when time is "t minus x" seconds ... awww, you know the rest
