The date time is set up under the settings (Language & Clock). I think that is OK. Seems to work fine.
In terms of the FTP client software, I am using the FTP Voyager. There seems to be no settings to preserve the date and time. However, I found a query that talks about the support for MDTM on the server. I am not sure on this functionality, but it appears to allow for the original date and time to be transferred to the server.
I will see if anyone ran into it on the EX2 forum.
Thanks for the feedback.
