How to subtract epoch times from WebParser and if X minutes old it will change font type

[364def49db]

I'm working on a Skin that will show my Glucose readings from Nightscout. However, I'm getting hung up on the time... I was wondering if someone could direct me in how I can accomplish subtracting the current time from the timestamp of the glucose and if it says more than 10 minutes old it can change the font to show the value is old.

Do I have to convert it out of epoch time, or can I simply do some math with it to determine if it's X minutes old?

You can get the timestamp of a value returned by a Time measure simply by the [TimeMeasure:TimeStamp] section variable (requires to add the DynamicVariables=1 option to the measure or meter where you want to use this - or in fact any - section variable).
However if a time is obtained through a WebParser measure, you have to use the value of that WebParser measure into a TimeStamp option of a Time measure and to use the timestamp of that Time measure. Not too complicated, but requires a little bit of experience in working with WebParser and Time measures.
So would be nice to post a sample code, in order to can get more specific help.

Here is the code I have thus far, and by no means am I an expert - novice as best.

Here is the WebParse: {"status":[{"now":1639959264062}],"bgs":[{"sgv":"108","trend":6,"direction":"SingleDown","datetime":1639959023000,"bgdelta":-17,"iob":"0","cob":0}],"cals":[]}

Clearly I"m not grabbing all aspects of this, just the ones that are important to me. So I would be doing the math from NOW and datetime and if past say X minutes to strike out the MeterGlucose text or to display a warning saying its out of date.

As you can tell, I haven't started anything with the time settings but was trying to figure out how to implement it.

[eclectic-tech]

Since both the 'now' time and the 'datetime' are both in epoch seconds, you can subtract those values and divide the result by 3600 (the number of seconds in 1 hour) to get the difference in minutes, then take actions based on that value.

This example code does that in [MeasureTimeDifference] calc measure and changes the glucose text color to red if over 60 minutes since the last datetime.

Code: Select all

[MeasureGlucoseTime]
Measure=WebParser
URL=[MeasureSite]
StringIndex=5

[MeasureTimeDifference]
Measure=Calc
Formula=(MeasureCurrentTime-MeasureGlucoseTime)
IfCondition=MeasureTimeDifference>3600
IfTrueAction=[!SetOption meterGlucose FontColor "255,0,0,205"][!UpdateMeter meterGlucose][!Redraw]
IfFalseAction=[!SetOption meterGlucose FontColor "#*colorText*#"][!UpdateMeter meterGlucose][!Redraw]

[MeasureTimeDifferenceFormatted]
Measure=Time
TimeStamp=[MeasureTimeDifference]
DynamicVariables=1

To test, I created a text file containing the webparser code you posted.
I also added a line of text with the time difference displayed below the measurement.
Of course, the trigger time and action(s) can be anything you want.

This should give you some ideas to make the skin change as you want.

EDIT: Use the difference in a time measure as the TimeStamp value to return a formatted view.

So I'm getting different results, when I use the code you give me and the meter it shows different "minutes" at almost every refresh. I'm talking 2 to 7, then 6, and 3 etc....

You mention dividing by 3600, but I do not see it anywhere in the code.

If I do the math manually say on this timestamp:

{"status":[{"now":1640141503742}],"bgs":[{"sgv":"106","trend":4,"direction":"Flat","datetime":1640141425000,"bgdelta":2,"iob":0,"cob":0}],"cals":[]}

1640141503742-1640141425000 = 78742

1640141503742-1640141425000 = 78742

Those timestamp values appear to be in milliseconds, so: 78742 / 1000 = 78.742 seconds. If so, you'd need to do this:

Code: Select all

[MeasureTimeDifference]
Measure=Calc
Formula=((MeasureCurrentTime-MeasureGlucoseTime) / 1000)
IfCondition=MeasureTimeDifference>3600
...

I have JUST figured this out this morning, I have it working now. For simplicity for now I'm going to keep it in miliseconds.

Doh! ... Thanks for catching my mistake. I usually just use the difference value as TimeStamp in a time measure and completely overlooked converting milliseconds in the calculation.
