the past several emails have time stamped the wrong time.
How do I correct this?

The timestamp on emails is based on your own timezone. Check the timezone settings under the “Viewing Email” section of the “More Settings” menu.
Thank you!

I propose that Yahoo provide a solution for its Pro version that enables the time stamp to be set. Mine is now for somewhere in the Pacific Ocean, and all "solutions" offered by Yahoo fail to work.
