Iran's parliament and the government have not yet reached a consensus on the country's official clock

[Alexander Krivenyshev]

Media continue conflicting reports about DST in Iran:
Article headline is "Iran will not observe DST" 
however one can read that: 
"....Majlis (Iran's parliament) may simply move ahead independently and 
seriously consider a recent parliamentary report in favor of the DST change... "
and
" ... a team of government representatives and members of the Majlis Research 
Center will hold meetings during the New Year holidays to make a final 
decision."
