How to identify the date of a returned value?

[Phillip Weeks]

This returns a (CW.past(MINUTE,backcounter).maximumValue) correctly...
I would like to know how to examine the timestamp on this pointvalue?

Hi Phillip,

Have a look at the .maximumTime property, https://help.infiniteautomation.com/about-mango-java-script/

Phil I am trying to use the new functionality of the meta recalculation. purge a timeperiod and recalc. I recall you saying the script process will now log an entry when it finishes, is this in 3.3 now?

I am trying to recalc a 1 day period and I check purge the data beforehand.
but the process seems to hang even on a short 1 day meta recalculation
with this script; It runs fine in simulation mode... any ideas what could be causing this?

var LITERS_LAST_5MIN;
if (CW.past(MINUTE,5).delta === Number.NaN){
LITERS_LAST_5MIN = 0;
} else {
LITERS_LAST_5MIN = CW.past(MINUTE,5).delta;
}
return LITERS_LAST_5MIN;

Yes, debug log messages were added for completion and checked exceptions. If there is a Logger in your Mango/classes/log4j2.xml for
com.serotonin.m2m2.meta.MetaEditDwr (or one of the parent packages). at debug level? Try adding this below the other <Logger/> tags and reloading your Log4J configuration on in the Log4J Reset section of the system settings.

<Logger name=" com.serotonin.m2m2.meta.MetaEditDwr" level="debug"/>

Edit: No offhand I don't know what's going on there. You may be able to see the point values have been deleted, and then you can watch them regenerate.

something screwy about this new history purge feature. I made a mistake entering the end date when I ran the first time and it created records back to 1969.
