Sometimes I get some strange Units in the Output, appendixes like Sqrt[-1/m]*Sqrt[-m] which could easily cancel each other out, but they dont; even when I use the Simplify/FullSimplify Command. It looks like

while it sholud look like "895.78 sek"

c = 299792458 m/sek;
G = 6.67384*10^-11 m^3/kg/sek^2;
M = 5.977*10^24 kg;
r2 = 6378000 m;
rs = 2*G*M/c^2;
r1 = rs;
\[Tau] =
1/c*\!\(
\*SubsuperscriptBox[\(\[Integral]\), \(r1\), \(r2\)]\(
\*FractionBox[\(1\),
SqrtBox[\(
\*FractionBox[\(rs\), \(r\)] -
\*FractionBox[\(rs\), \(r2\)]\)]] \[DifferentialD]r\)\)

Then it gives me the right solution, but appendet with unneccessary Sqrt[-1/m]*Sqrt[-m]instead of shortening it to -1...
