I think the SE is updated from the HMC. FWIW, we keep the timezone on the HMC to 0 and let the OS's make the proper adjustment. It makes the twice yearly time changes a snap.

You can set the time from the HMC to the SE's if you want, but I believe it is a manual process.

Now if we can get Mr. Altmark or Mr. Bitner to confirm (in other words, "Dudes, please reply to this!") you just solved an incredibly huge problem for us.
