java - ZonedDateTime to UTC with offset applied? -

i using java 8
zoneddatetime looks

2013-07-10t02:52:49+12:00 

i value

z1.format(datetimeformatter.iso_offset_date_time) 

where z1 zoneddatetime.

i wanted convert value 2013-07-10t14:52:49

how can that?

is want? converts zoneddatetime localdatetime given zoneid converting zoneddatetime instant before.

localdatetime localdatetime = localdatetime.ofinstant(z1.toinstant(), zoneid.of("utc")); 

or maybe want users system-timezone instead of hardcoded utc:

localdatetime localdatetime = localdatetime.ofinstant(z1.toinstant(), zoneid.systemdefault());
