Default RedShift 5: Observing the ISS, wrong time

Hello!

I'm using RedShift 5 and I want to observe the ISS at my location. Therefor
I'm updating RedShift with the latest Two Line Elements (TLE) of ISS.

But when I compare the times of the maximum elevation about the horizon with
other pages using the SAME TLEs, there's always a differnce of more than 1
minute, which is 500 km of ISS flight!

This difference is constant the following days. The difference is just the
time, the maximum angles about horizon are correct.

What's the reason of this problem?

Not sure about Redshift, but for tracking satellites I use this. It's free,
and it's very good.
