Im struggling with using time in ezscript.
I want to check how long it has been since a given face was recognized. But all the time functions seem to give strings and I cant really figure out how to convert those to number and compare. Using the script help I came up this this:
if ( FmtTimeSpan(CDateTime(now()) - CDateTime($lastfacedetection) ), "mm") >5))
but that doesnt work, it tells me: Operator '-' invalid for strings.
