The TIME$ Function returns a STRING representation of the current computer time in a 24 hour format.


Syntax

PRINT "Present time = "; TIME$


  • Returns the present computer time in hh:mm:ss 24 hour format: "19:20:33"
  • Uses 2 colon (:) separators between hours, minutes and seconds
  • Hour values range from "00" to "23" starting from midnite.
  • Minutes and seconds range from "00" to "59"
  • Continuous TIME$ calls may lag if a QBasic program is minimized to the taskbar!


Example 1: A simple clock using DRAW with Turn Angle.

  
SCREEN 12
DO
    CLS
    t$ = TIME$: h = VAL(t$): m = VAL(MID$(t$, 4, 2)): s = VAL(MID$(t$, 7, 2))
    PRINT t$
    CIRCLE STEP(0, 0), 200, 8
    DRAW "c12ta" + STR$((h MOD 12) * -30) + "nu133"
    DRAW "c14ta" + STR$(m * -6) + "nu200"
    DRAW "c9ta" + STR$(s * -6) + "nu200"
    _DISPLAY
    _LIMIT 1
LOOP UNTIL INKEY$ = CHR$(27)  
Code by Galleon
Explanation: Note that VAL(TIME$) can just return the hour number 0 to 23 as the read stops at the first colon.


Example 2: The following Function converts TIME$ to normal 12 hour AM-PM digital clock format.

  
PRINT TIME$
PRINT Clock$

FUNCTION Clock$
hour$ = LEFT$(TIME$, 2): H% = VAL(hour$)
min$ = MID$(TIME$, 3, 3)   
IF H% >= 12 THEN ampm$ = " PM" ELSE ampm$ = " AM" 
IF H% > 12 THEN
  IF H% - 12 < 10 THEN hour$ = STR$(H% - 12) ELSE hour$ = LTRIM$(STR$(H% - 12))
ELSEIF H% = 0 THEN hour$ = "12"          ' midnight hour
ELSE : IF H% < 10 THEN hour$ = STR$(H%)  ' eliminate leading zeros   
END IF  
Clock$ = hour$ + min$ + ampm$
END FUNCTION  
14:13:36
 2:13 PM
Explanation: When hours are less than 10 (but not 0), Template:KW(H%) alone keeps a space ahead of the hour. For 2 digit hours, Template:KW is used to remove that leading space. For the hours of 10 AM to 12 PM, the hour Template:KW value is passed from Template:KW(TIME$, 2) at the beginning of the function.
