UKismetMathLibrary::LessEqual_DateTimeDateTime
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if A is earlier than or equal to B (A <= B). Use when you need to verify that an event is scheduled no later than a given deadline.
Caveats & Gotchas
- • The equal case is tick-precise — two FDateTime values obtained from separate FDateTime::UtcNow() calls will virtually never be equal. This function effectively behaves like Less_DateTimeDateTime for real timestamps.
- • When used in Blueprint with the <= node, both input pins default to a zero-initialised FDateTime (year 1, January 1) if not connected. Ensure both pins are wired to avoid always-true comparisons.
