UKismetMathLibrary::MakeTimespan2
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Constructs an FTimespan from days, hours, minutes, seconds, and a nanosecond fraction. Use this variant when you need sub-millisecond precision; prefer MakeTimespan when millisecond resolution is sufficient.
Caveats & Gotchas
- • FractionNano is the sub-second nanosecond component, not total nanoseconds — valid range is 0 to 999,999,999. Passing values outside this range will produce an incorrect timespan without error.
- • FTimespan stores time internally as int64 ticks (100-nanosecond intervals), so FractionNano is rounded to the nearest 100 ns before storage.
