[Geysers] Morning data--glitch in geysertimes.org (Young)

[Jacob Young]

Hi All,
I have fixed this error in GeyserTimes as reported by Lynn Stephens.

It was actually a Daylight Saving issue and was affecting all geyser entries, not just Morning.  It was also just a reporting issue and not a storage issue.  All entry times were appearing correctly EXCEPT when using the detailed search feature and the time was during the "summer."  Winter times were not off by one hour.  This has only been an error since the latest feature release a few weeks ago so that's why no one caught the error earlier.

To give you all some transparency into how GT stores and maybe restore your confidence in GT a bit:
Entries are converted into Unix Epoch time (http://www.epochconverter.com/) and stored in the database as a single number.  This process has not had errors on GT.  Reporting of eruption times requires converting from Unix Epoch to MST/MDT.  This conversion happens for each entry time you see on GT.  Because of the added complexity of the detailed entry search, I was using a different function to do the conversion that did not account for Daylight Saving Time.

As a plea from programmers everywhere, write or call your congressman and request a repeal of Daylight Saving Time!

Thanks,
Jake

Scott has found a glitch in geysertimes.org. The entry for the 2012-06-30 eruption of Morning is correct at 0616.  However, the retrieve/detailed entry search function of geysertimes.org is currently subtracting an hour from every eruption time.  The Retrieve/Detailed Entry Search function subtracted an hour from every eruption time from every geyser I checked.  Jake is working on the situation.
 
Jake may have found the solution before this email gets sent out to the listserv, but if you have been using data extracted from geysertimes.org via the the retrieve/detailed entry search function, you'll need to check the output against original entry using one of the other functions to make certain the times are not an hour off.  Intervals calculated from the data set will be correct since every value is off by the same amount, but the raw values may not be correct.
 
In the meantime, let me reiterate my thanks to Jake for creating and maintaining geysertimes.org.

My bad: that time to correct the record should read 06:16, not 06:06.

Many  thanks to Lynn, Will, etc. for their work on geysertimes.org, and for putting  together the list of Morning Geyser eruptions. I do, however, have one  correction, namely the eruption I (with Lynn and Mary Beth) saw: 2012-06-30.  It was at 06:06 when I saw that steam cloud go up and I know that  time was very near start.
