Compare 2 Time/Date values to determine which is older.

I am writing a piece of code to find schematics that are "older" than their respective layout views, is there a clean way in SKILL to compare 2 time/date strings to see which is older? Below is the format I will be comparing.

"Jul 11 21:21:16 2024"

    You can use the SKILL function "stringToTime" to convert a date/time string into an integer value representation (that can be used for comparison).

    For example:


    time1 = "Jul 11 21:21:16 2024"
    time2 = "Jul 11 21:21:16 2025"
    printf("%L is %s than %L\n" time1
      if(stringToTime(time1) < stringToTime(time2) "earlier" "later")
      time2)

    Or even simpler, just use compareTime() on the two date strings you have.
