Re: [las_users] LAS-OPeNDAP : time axis update for forecast data

[Roland Schweitzer <Roland.Schweitzer@xxxxxxxx>]

Hi Dmitri,

This is a known issue with LAS.  Your best bet now is to update the XML 
and run genLas.pl again.  It might be possible to put these steps in a 
script and run it everyday with a cron job.  You can use the update 
option on genLas.pl to make the downtime as short as possible.

When the contents of remote file changed, there will no data for the time period in LAS xml file and LAS will give error.
