[Adam Shand <larry@alaska.net>]

any body have this problem and no how to solve it?

heyzeus(larry)$ smtm
ERROR: Date::Manip unable to determine TimeZone.
   Date::Manip::Date_TimeZone called at /usr/lib/perl5/Date/Manip.pm line 615
   Date::Manip::Date_Init() called at /usr/lib/perl5/Date/Manip.pm line 1315
   Date::Manip::ParseDate('today') called at /usr/bin/smtm line 68

it's not a permissions problem cause i tried running it with sudo and i get
the same thing.

thanks,
adam.
