<TITLE>London (GMT) notation self-conflicts</TITLE>

<P><FONT FACE="Times New Roman">Hello,</FONT>
<BR><FONT FACE="Times New Roman">My company's application servers use the Olson database as a time zone reference. <BR>
The following listings appear, which I believe are so-named in the Olson database:</FONT>
<BR><FONT FACE="Times New Roman">London (Greenwich Mean Time)<BR>
Belfast (Greenwich Mean Time)<BR>
Dublin (Greenwich Mean Time)<BR>
</FONT>
<BR><FONT FACE="Times New Roman">These notations are correct only in winter, when all three cities are on GMT.<BR>
But in Summer, these cities are GMT+1.<BR>
This means that in summer, there is a conflict within the notation.</FONT>
<BR>
<BR><FONT FACE="Times New Roman">Note that this conflict does not arise for cities outside the United Kingdom.<BR>
Taking Paris (Central European Time) as an example, Paris time and Central European Time are always the same, irrespective of the extra hour of Daylight Savings offset from GMT in summer.<BR>
<BR>
To fix this, "Greenwich Mean Time" should be removed from the notation for London, Belfast and Dublin.<BR>
It might be replaced by "United Kingdom Time," "British Isles Time" or "British Time."</FONT>
<BR><FONT FACE="Times New Roman">Does this conflicting notation indeed exist in the Olson database and, if so, can it be fixed?</FONT>
<BR><FONT FACE="Times New Roman">Thanks for your help,<BR>
