The NSIS config file for symbian packages does not have the MODULE_LICENSECHECK_PACKAGEDATE variable defined. This means that for a commercial customer, the package will expire when the license expires – they should actually be able to use the pacakge in perpetuity, as long as the pacakge was generated before their license expired.

The bug occurs because the symbian pacakge config doesn't have an "installer buildDir" step. Setting the package date probably doesn't belong in that step anyway, and should be moved to a different step.
