iacisrmma,
Don’t forget to correct for the time difference to Jerusalem local solar time.
This equals the time difference to Israel minus the difference between the local solar time there and the mean Israeli time which is quite a bit off the center of the time zone. The difference to subtract is exactly 20 minutes and 56.5 seconds at the longitude of the temple mount.
