When you susbtract times, the result is seconds, You must convert seconds to Time string, before replace

thisform.text1.value=ftime()
thisform.text2.value=stime()
thisform.text3.value=SecToTime(thisform.text2.value-thisform.text1.value)
replace time1 with thisform.text1.value,;
        time2 with thisform.text2.value,;
        time3 with thisform.text3.value

FUNCTION SecToTime(nSecs)
   LOCAL c_hours, c_min, c_znak
   IF nSecs == 0
       RETURN ""
    ENDIF
    c_znak  = IIF(nSecs < 0, "-","")
    nSecs   = ABS(nSecs)
    c_hours = INT(nSecs/3600)
    nSecs   = nSecs - (c_hours*3600)
    c_hours = IIF(c_hours<10,"0","")+ALLTRIM(STR(c_hours,15))
    c_min   = INT(nSecs/60)
    nSecs   = nSecs - (c_min*60)
    c_min   = IIF(c_min<10,"0","") + ALLTRIM(STR(c_min,15))
    nSecs   = IIF(nSecs<10,"0","") + ALLTRIM(STR(nSecs,10))

RETURN c_znak+c_hours+":"+c_min &&+":"+nSecs
