UKismetMathLibrary::NotEqual_DateTimeDateTime
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if two FDateTime values do not represent the same point in time. Equivalent to !(A == B) at tick precision.
Caveats & Gotchas
- • Two timestamps obtained from successive FDateTime::UtcNow() calls will almost always be not-equal, even if called milliseconds apart, because the system clock advances between calls.
- • This is a tick-exact comparison. Two dates that represent the same calendar day but differ by even one tick will return true — use date-component comparisons (GetDay, GetMonth, GetYear) if you want day-level equality.
