My.tupperware email account question

[TupperwareinMisawa]

Does anyone know how to change the time zone listed for your emails? I'm in Japan and it's so far off, it's hard to tell when mail has actually been sent!
Thanks!

If you go into you Contact Center from My.Tupperware, there is a link at the upper right hand corner that says Preferences. When I clicked on that, I found a link to change your time zone. Unfortunately, when I clicked on it, it said that the page couldn't be found. I am going to post a note on the My. Tupperware message board for the techies. Hopefully, they will be able to correct it in a hurry....
