Hello,

 

I am trying to understand the best way to handle DST (and differing timezones as well) when requesting from the Archiver.  In the documentation I did find this one sentence “The times are in UTC; so any conversion to local time needs to happen at the client.” 

 

That leaves me with 2 questions, one about DST and one about time zones in general and requesting in matlab/python etc

 

1. Does this mean then that when I do a URL request I need to account for what time zone the data was taken in?  Example I run the archiver in PST, data is stored at 1pm PST.  When I go to retrieve that data I need to put in the request 2012-012-27T01:00:00.000-800Z. If the data was taken in MST instead of PST then the URL would have to account for that and the it would now have to be 2012-012-27T01:00:00.000-700Z instead? 
2. If the data was taken in DST same sort of question applies, I assumed the archiver handles DST but my request still has to account for the change.  Example data taken after March 13^th 1pm PDT the request would look like 2012-05-27T01:00:00.000-700Z and if it was outside DST request is 2012-012-27T01:00:00.000-800Z.

 

Just need clarification that the client doing the URL Request must add in the proper time zone where/when data is stored in Zulu  and DST.

 

Thanks,
