"If scr is wrng then it has done mistake by changing schedule of simhapuri years back only"
Yes, it's a mistake only, w.r.t 12710 and later w.r.t 12709
Firstly RSA with Devagiri is first BIG fault.
Later because of Devagiri incoming, timings have been changed from 21.30 to 22.00 and 22.30 later, now it's 22.55
