    Using
    Code:
    Dim span as Period
    I want to get the time difference between 2 times.
    I tried using on a button click
    Code:
    Dim span2 As String
    span = DateUtils.PeriodBetween(StartTime, endTime)
    span2 = span
    Msgbox(span2,"")
    and then the message box shows:
    java.lang.NumberFormatException: Invalid double: "[Days=0, Hours=0, IsInitialized=true, Minutes=0, Months=0, Seconds=14, Years=0]"

    How can I change it so it appears as 00:00:14 ?

    You need to convert the period to such formatted string. It will not happen automatically.
    Code:
    Sub PeriodToString(p As PeriodAs String
       
    Return $"$2{p.Hours}:$2{p.Minutes}:$2{p.Seconds}"$
    End Sub
    Log(PeriodToString(span))

    Code:
    span2 = numberformat(span.Hours,2,0)&":"&numberformat(span.Minutes,2,0)&":"&numberformat(span.Seconds,2,0)

    Thanks Erel. One more question.
    Is it possible to check if the time span is greater than another time span? I already used
    Code:
    StateManager.SetSetting("Prevtime",PeriodToString(span))

    'Check if span is greater
    If PeriodToString(span) > StateManager.GetSetting("Prevtime"Then
    Msgbox("You have beat your record","")
    End If

    It is possible, but you will need to write the code that checks it. If you are only dealing with hours or smaller intervals then it is quite simple to convert the Period to seconds and then compare it:
    Code:
    Sub ShortPeriodToSeconds(p As PeriodAs Int
    Return p.Hours * 3600 + p.Minutes * 60 + p.Seconds
    End Sub
