Set a UTC+11 (Australia/Sydney) time zone on commons. Try to upload an image. UploadWizard complains, the date you are trying to set it in the future'. This happens frequently, as often I indicate a today date for my uploads (perhaps whenever it is more than 11AM in my area? I am not sure what exactly is the time of day when this bug occurs, but this is my hypothesis). But I'd prefer it to

• show my timezone
• show my current time
• allow me to choose the date in my timezone

This way we would

• ensure that the user has set their timezone correctly and is indicating the date in the correct time zone, and
• have a chance to convert the date from the user's time zone to UTC or whatever standard the date is stored in.
