ΔT, Delta T, delta-T, deltaT, or DT is the time difference obtained by subtracting Universal Time (UT) from Terrestrial Time (TT): ΔT=TT−UT.
Universal Time is a time scale based on the Earth's rotation, which is somewhat irregular over short periods (days up to a century), thus any time based on it cannot have an accuracy better than 1 : 108. But the principal effect is over the long term: over many centuries tidal friction inexorably slows Earth's rate of rotation by about +2.3 ms/day/cy. However, there are other forces changing the rotation rate of the Earth. The most important one is believed to be a result of the melting of continental ice sheets at the end of the last glacial period. This removed their tremendous weight, allowing the land under them to begin to rebound upward in the polar regions, which has been continuing and will continue until isostatic equilibrium is reached. This "glacial rebound" brings mass closer to the rotation axis of the Earth, which makes the Earth spin faster (law of conservation of angular momentum): the rate derived from models is about −0.6 ms/day/cy. So the net acceleration (actually a deceleration) of the rotation of the Earth, or the change in the length of the mean solar day (LOD), is +1.7 ms/day/cy. This is indeed the average rate as observed over the past 27 centuries.

T
Te regalo mi cintura,
Y mis labios para cuando quieras besar,
Te regalo mi locura
Y las pocas neuronas que quedan ya.
Mis zapatos desteidos,
El diario en el que escribo,
Te doy hasta mis suspiros,
Pero no te vayas ms,
Porque eres t mi sol,
La fe con que vivo,
La potencia de mi voz,
Los pies con que camino,
Eres t, amor,
Mis ganas de rerme,
El adis que no sabr decir
Porque nunca podr vivir sin ti.
Si algn da decidieras,
Alejarte nuevamente de aqu,
Cerrara cada puerta,
Para que nunca pudieras salir.
Te regalo mis silencios,
Te regalo mi nariz,
Yo te doy hasta mis huesos,
Pero qudate aqu,
Porque eres t mi sol,
La fe con que vivo,
La potencia de mi voz,
Los pies con que camino,
Eres t, amor,
Mis ganas de rerme,
El adis que no sabr decir
Porque nunca podr vivir sin ti.
the body count will be massive
much worse than Oklahoma
hard times for the experts
messes like this mean lots of work
burnt beyond recognition
IDs they get from DNA
and everybody will still wonder
how we ever let it happen
a car filled with explosives
made its final fucking run
splitting crowds in mere seconds
like Moses once split the red sea
just moments later an explosion
even brighter than the sun
they hadn't time to realize
what was going on
we just got another lesson
how illusory safety is
this was an opportunity
just too good to miss
we have been gutted like a fish
in a moment of poor attention
now we are responsible
for our own suspension
Hey baby can’t you see,
this is what u did to me
I’m so far from joy;
I don’t want to be your toy
My heart keeps telling me,
I should be with you
no more I want to get out,
from this misery,
don’t know what to do
Everyday I spent my time with you.
So depressed
Having all regrets.
The more I see your face
Just can’t take it any more.
I love to stay away
From your over sense of self
Driving on the highway
Seeking means from time to time
Some might, say,
bizarre is what you are.
But I believe time can change it all.
You’re just a simple girl with a special kind of life.
Unsure of everything.
Going nowhere with Your mind
