android ics: date/time is restored to 1970/XX/XX after phone encryption, is this an issue?
===

since Android ICS supports phone encryption, I try this feature today, but I  found that after performing phone encryption, system date/time is restored to 1970/XX/XX, is this an issue? 
if not, I don't think this is an user friendly design.
if yes, why does it restore to 1970s? I just encrypt my phone not factory reset?
