Hello to all,
As earlier announced, here-below a comparison of our results.
I have used a method similar to the one published by Jean Meeus in Astronomical Algoritms .
Jupiter / Mars
Saturn / Mars
and 2546.1 arc secs.
and 3259.8 arc secs.
10:37:52 UT1 on 20 March, 2020
at about 17:30:30 UT1 on 31 March, 2020

20 March 2020 close to 10:37:21 UT (TT-UT = 69,7 s)
2,546 arc seconds
31 March 2020 close to 10:32:15 UT (TT-UT = 69,7 s)
3,260 arc seconds
All results are almost the same. And the method derived by Sean is quite efficient !
