I am running a local EMONCMS on a EMONPI and use JSON to extract feed data using the command:
to extract half hourly power consumption.
This works fine, except when the start and end UNIXTIME are crossing the changeover from/to daylight saving time (DST).
When gaining a DST hour, the extra two half hours are not extracted.
When losing a DST hour, the missing hour is still extracted as if the day had 24 hours.
However, when using my local EMONCMS web front end, the missing and extra hour are correctly reflected in the graphs by showing 50 half hour periods and 46 respectively.
Is there a way to extract the feed data with the correct number of half hour periods when crossing the DST change over?
Many thanks in advance for sharing your insights.
