<div>Hello IANA team,</div>
<div> </div>
<div>This is Mengzhe Hu from Juniper Networks Advanced TAC. </div>
<div><font face="Times New Roman"> </font></div>
<div>Here we are importing the IANA Time Zone Database to Junos referring to the two pages below:</div>
<div>Juniper page:<a href="http://www.juniper.net/documentation/en_US/junos13.3/topics/task/configuration/time-zone-custom-configuring.html" target="_blank"><font color="#0563C1"><u>http://www.juniper.net/documentation/en_US/junos13.3/topics/task/configuration/time-zone-custom-configuring.html</u></font></a></div>

<div>But from the latest <a href="ftp://ftp.iana.org/tz/tzdata-latest.tar.gz" target="_blank">tzdata-latest.tar.gz</a> , we can’t find the corresponding change reflecting the Moscow, Russia government time zone change.</div>
<div>Please refer to the following page:</div>
