Hi all, firstly, it seems we are using a bunch of time functions that are not thread-safe (localtime gmtime and asctime) (See recommendation here: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/sy...) - so I'll push up a p/r for that. Next is the couple of Metrics that are using the unit 'Seconds' but which are really time_t values.. I'm looking to add a new Group of metrics for time with units UnixEpoch, UTCDate & LocalDate. This is what I have at the moment with the default metrics for m.time.utc as UTCDate and v.p.gpstime as LocalDate. (I can make them the same) m.time.utc 2023-10-19 11:22:28 UTC v.p.gpstime 2023-10-19 19:22:26 AWST Currently I've changed these in the JSON to be exported as "%FT%T.000Z" which is a semi standard for JSON. The 'conversion' for the date values doesn't do anything - these really only effect the output. I've also been looking at v.g.timerstart which is UTCTime & LocalTime units. I've fixed up conversions both way.. v.g.timerstart 18:00:00local Thoughts on these? Cautions? //.ichael
