There is no direct evidence of the year of a defeat of Khengara. Bhagwanlal Indraji assumed that Sajjana was the governor of Saurashtra based on the Girnar inscription dated VS 1176 (1120 CE) but no such inscription is found and the only inscription of Jayasimha in Girnar is undated and does not mention Sajjana. The Vividha Tirth Kalpa mentions that Sajjana, the governor of Saurashtra, built Neminatha temple on Girnar in VS 1185. The Prabandha-chintamani mentions that Sajjana spent three years' revenue in building the temple. If it is true, Sajjana was the governor of Saurashtra in VS 1181-82 (1125-26 CE). So Saurashtra might have been won before that 1125-26 CE.
