When you install Wubi - before you reboot it sets up a file C:\ubuntu\install\custom-installation\preseed.cfg which contains instructions to ubiquity on how to install (including the timezone). e.g. in mine it shows:
## CLOCK AND TIME ZONE
d-i clock-setup/utc boolean false
d-i time/zone string America/Vancouver
This file is removed after the install, so you would have to reinstall to see it. The question is, is Wubi providing the incorrect instruction to Ubiquity or is Ubiquity failing to set it correctly.
