Thanks, fine, seems to be easier to do with Time than with DateTime
(strange enough!)

even i've corrected datetime with tzinfo, gave the correct hour with a
false time zone, strange...

here the datas :
utc_datetime_str = '2010-06-12T07:34:29UTC'
tz = TZInfo::Timezone.get('Europe/Paris')
local = tz.utc_to_local(utc_datetime)
# --> local = 2010-06-12T09:34:29+00:00

here the hour is correct BUT the time zone :
local_zone = local.strftime(fmt='%z')
# --> local_zone = local.strftime(fmt='%z') = +0000

I'll switch to Time )))
