Creating Timer in Oracle D2k / Forms 6i and Displaying a Clock
This is about timer in D2kAn external clock can be constructed using timers. Timers correspond to internal clocks, which have a specific time period. When the specified duration expires, the timer can either perform an action once and stop or repeat the action regularly every time the timer expires. Timer duration is always in milliseconds. Timers are created using the CREATE_TIMER built in and require a WHEN-TIMER-EXPIRED trigger to be written at the form level. This trigger fires every time the timer expires.
