invalid lvalue in assignment

The red line is where the compiler tells me there is an error: invalid lvalue in assignment. Help please

Code:

#include <stdio.h>
#include "genlib.h"
#include "simpio.h"

void GetTime(long SysSecs, int *hours,int *minutes,int *seconds);
main()
{
    long SysSecs;
    int hours, minutes, seconds;
    printf("Enter device seconds: ");
    SysSecs = GetLong();
    GetTime = (SysSecs, &hours, &minutes, &seconds);
    printf("Time is: %d:%d:%d\n", hours, minutes, seconds);
}
void GetTime(long SysSecs, int *hours,int *minutes,int *seconds)
{
    *hours = SysSecs / 3600;
    *minutes = SysSecs / 60;
    *seconds = SysSecs % 60;
}

> GetTime = (SysSecs, &hours, &minutes, &seconds);
Why are you using = here?

You're trying to call the function.
See your prior call to printf for how that works.

You should not assign the arguments to a function.

Code:

GetTime(SysSecs, &hours, &minutes, &seconds);

lvalue (short for left value) refers to it's position related to the assignment operator '='.

oh dear god..result of my tiredness..THANK YOU!!!
