Thanks for bringing this to our attention. Searching in <a href="http://unicode.org/cldr/data/common/supplemental/supplementalData.xml">http://unicode.org/cldr/data/common/supplemental/supplementalData.xml</a> for "GMT+5", I see:<br>
<br><b>a windows mapping</b><br><mapZone other="US Eastern Standard Time" type="Etc/GMT+5"/><br><br>From the statement, it looks like the issue is with this line. I believe that this was touched relatively recently by a Microsoft engineer. The actual data is just mapping the windows ID "US Eastern Standard Time" to the TZDB ID "Etc/GMT+5". I'm not sure what "Change the daylight flag." means, since there is no daylight flag associated with Etc/GMT+5. But I'm not an expert on this area, so I'll forward to people who are more conversant.<br>
<br>The item about Indiana is just a comment, and does look spurious: <!-- S (GMT-05:00) Indiana (East) -->. <br><br clear="all">Mark<br>
<br>P.S. Note: there are other items mentioning GMT+5, but I think they are not relevant:<br><br><b>a zone item (territory and alias)</b><br>
<zoneItem type="Etc/GMT+5" territory="001" aliases="EST SystemV/EST5"/><br>

<br>
"Etc/GMT+5" would have been correct for much of Eastern Indiana through 2006 since DST wasn't observed.<br>
(Recall that there's a UNIX-heritage GMT offset sign reversal; use the commands...<br>
TZ=Etc/GMT+5 date<br>
TZ=EST date<br>
TZ=EST5 date<br>
...to see that Etc/GMT+5 used to be the right thing.)<br>
<br>
Perhaps this particular CLDR data hasn't been updated since 2006.<br>

Hi,<br>
<br>
My team has located and fixed an issue in the CLDR supplemental data for Windows TZ mapping.<br>

Indiana (East) Mapping<br>
<br>
Changes...<br>
1. Change the Etc/GMT+5 type which seems spurious.<br>
2. Change the daylight flag.<br>
<br>
<br>
Original...<br>
<mapZone other="US Eastern Standard Time" type="Etc/GMT+5"/><br>
<!-- S (GMT-05:00) Indiana (East) --><br>
<br>
Updated...<br>
<mapZone other="US Eastern Standard Time" type="Indiana (East)"/><br>
<!-- D (GMT-05:00) Indiana (East) --><br>
<br>
<br>
Could you verify?<br>
