date_time local to UTC conversion

hi.

i am using boost::date_time

i am using ptime always in UTC. but some time i have to interact with
user.

therefore i need to convert the ptime to the local ptime back and forth.

int foo ()
{
   ptime mytime_asutc = some_UTC_time;
   ptime mytime_aslocal = XXX (mytime_asutc);

   ptime histime_aslocal = some_local_time;
   ptime histime_asutc = YYY (histime_aslocal);
}

i am in germany, so i'd like to use germany local settings. best would
be to get all information from unix TZ variable. but i found out, only
one direction of conversion works with unix TZ. the other one needs
manual input. i don't understand the eu_dst_trait stuff.

i'd very much appreciate to have XXX and YYY.

cu & thx
erik
