UKismetMathLibrary::Subtract_TimespanTimespan
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns A - B as a new FTimespan. The result can be negative if B is larger than A, which is a valid FTimespan state.
Caveats & Gotchas
- • A negative result is perfectly valid and represents a timespan going backwards — check the sign with GetTotalSeconds() < 0.0 before displaying it.
- • In C++ prefer the FTimespan - operator for clarity; this wrapper exists to expose subtraction to Blueprint.

FTimespan Example
Compute remaining time C++
FTimespan Deadline = FTimespan::FromMinutes(10.0);
FTimespan Elapsed = FTimespan::FromMinutes(3.5);
FTimespan Remaining = UKismetMathLibrary::Subtract_TimespanTimespan(Deadline, Elapsed);
// Remaining == 6.5 minutesTags
