UKismetMathLibrary::FromSeconds

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Constructs an FTimespan from a number of seconds. The most frequently used FTimespan factory in gameplay code because most engine APIs expose durations in seconds.

Caveats & Gotchas

• When bridging from UWorld::GetTimeSeconds (a float in older projects), note that float precision limits accuracy to roughly ±16 million seconds (~6 months). Cast to double before passing to avoid rounding that accumulates over long sessions.
• FromSeconds does not clamp the input — supplying a NaN or infinity from a bad calculation will produce an invalid FTimespan whose tick value is implementation-dependent. Validate inputs from external sources.
