Logic Gate

I have added "XOR" Gate to my PM and in that i have added a condition like
"if(
totime(local(now(), "IST")) = cons!IT_TIME_CONSTANTS_FOR_VERSE,
true(),
false()
)

Where The constant holds time of 12:30 PM,
but even though that expression is true the Pm is returning false because of which XOR is failing.

Can anyone suggest what's wrong here

Thanks in advance,
SSP
