Update time zone data files to tzdata release 2014j for DST law
changes in Russia and elsewhere
</para>
<para>
This change is more significant than most time zone updates because
many Russian zone abbreviations are changing meaning, including IRKT,
KRAT, MAGT, MSK, NOVT, OMST, SAKT, VLAT, YAKT, and YEKT.
<productname>PostgreSQL</> will now associate the correct UTC offset
