Re: TimeZone bug again.....

Hi

It seems that because to_timestamp does a time-zone conversion it is
upsetting are attempt to load legitimate data...

Is it possible (similar to the to_date fix that was done some time ago by
tom lane) to have a similar
method like "to_timestamp_raw" or something that will store/retrieve
date-times as given in format/data
without doing any datetime timezone conversions?

This is going to be the only way that our data which spans form 1800 to
today and any time
specified can be stored and accurately retrieved..

Daylight savings etc we handle outside the database records...

Ie lsd stands for local standard time and tm represents UTC time which are
the
two times that we store...

Any help greately appreciated...

These date-time bugs are stopping us from advancing our climate database on
the external web using postgresql at the moment...

(If you cannot fix it can you tell me where in the src code the time-zone
conversion is done and I will comment it out or something...)

Cheers
Arn
