# Time and Date

The following commands provide a simple way of putting the current system time and date into the currently active input buffer:

S21
U147F
T

1
2
3

Puts the current time, in internal format (seconds since midnight), in the current input buffer (in this case, %21).

S10
U147F
D

1
2
3

Puts the current date, in internal format (days since 31 Dec 67), in the current input buffer (in this case, %10).

S8
U147F
T MTS

1
2
3

Puts the current time, in external format (MTS yields hh:mm:ss), in the current input buffer (in this case, %8).

S33
U147F
D D2/

1
2
3

Puts the current date, in external format (D2/ yields dd/mm/yy or mm/dd/yy - depending on your internationalization settings), in the current input buffer (in this case, %33).

# Validating Time and Date

You can use pattern matching to input a valid date or time but it does not catch input like 10/32/94 or 25:25:25.

The example below checks for a valid date in D2/ format by converting it. This mechanism works because an invalid date converts to null.

PQN
10 T "Enter date (mm/dd/yy) :", +
IF # %1 XFinished
IBP %1
MV %2 "
IBH%1;D2/;
IF # %2 T B,"Oops!"\ GO  10
C Date OK
