Depending on where I go to get a good understanding of the Lorentz transformations, I run into two formulas for time (t):(adsbygoogle = window.adsbygoogle || []).push({});

[tex]T=T_0 * \frac{1}{ \sqrt{ 1-\frac{v^2}{c^2} } }[/tex]

and

[tex]t=\left( t' + \frac{vx'}{c^2} \right) * \frac{1}{ \sqrt{ 1-\frac{v^2}{c^2} } }[/tex]

What is the explanation for having these two different formulas for time? If there was only one or the other, it would make sense to me but I can't understand how there can be two.
