void Time_adjustCurrentDateTime

(

void

Definition at line 43 of file Time.c.

{
    g_SystemDateTime += SECOND; 
}

void Time_getCurrentDateTime

(

tDateTime *

psDateTime

)

This function can be used to get the current time.

{
    *psDateTime = g_SystemDateTime; 
}

void Time_initSystemDateTime

(

void

)

Definition at line 25 of file Time.c.

{
    g_SystemDateTime = 0;
    // every time when the Timer_A is overflowed adjust the current time by 1 (sec)
    Interrupts_setTimerA_ISRCallbackFunction(&Time_adjustCurrentDateTime);
