Testing for empty value

[mike]

I have the following code

print "date times",@date,br;
if ($ti1){
print "time 1 is not empty";
}
else {
print "time 1 is empty";
}

If there is a value it works but not if there isn't ie:
if there is a value it prints "time 1 is not empty", but if there is not
nothing comes out

anyone any ideas?
