Measure time a function has taken

[SaxonRah]

Maybe the time and date stuff will help you

//Capture the current time stamp and format it to YYYY-MM-DD HH:MM:SS.mmm.
FDateTime CurrentDateAndTime = FDateTime::UtcNow();

this is a Formatted Time Stamp in an FString (also other examples for CurrentDateAndTime)

//Capture the time stamp.
FString FormattedTimeStamp = FString::Printf(TEXT(“%04i-%02i-%02i %02i:%02i:%02i.%03i”), CurrentDateAndTime.GetYear(), CurrentDateAndTime.GetMonth(), CurrentDateAndTime.GetDay(), CurrentDateAndTime.GetHour(), CurrentDateAndTime.GetMinute(), CurrentDateAndTime.GetSecond(), CurrentDateAndTime.GetMillisecond());
