Keeping the date and time as I move points

[RsH]

Thank you for making this change. I find that I can insert points, move points and then refine the positions of the points via use of the 'speed' calculation. I then get the inserted points in approximately the correct position relative to those I have not moved by keeping the speed within a kilometer an hour of the original speed. At the distances I am working with, the errors will only be on the order of a few meters, which are no more than the errors of the GPS in the first instance. Having to play with the date and time for every moved point was just one added obstacle to successfully refining the points, particularly in a city where tall buildings shift the points via reflection of satellite signals.
