UKismetMathLibrary::DateTimeFromString

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Parses a date/time string in UE's native format (the format produced by FDateTime::ToString()) into an FDateTime. Returns true on success, false if parsing fails.

Caveats & Gotchas

• This function expects UE's own ToString() format ('YYYY.MM.DD-HH.MM.SS'), not ISO-8601. Passing an ISO string will fail — use DateTimeFromIsoString() instead.
• Like DateTimeFromIsoString, Result is not cleared on failure. Always validate the return value before using the output.
