UKismetMathLibrary::FromUnixTimestamp

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Converts a Unix timestamp (seconds since 1970-01-01 00:00:00 UTC) into an FDateTime. The resulting value represents UTC time.

Caveats & Gotchas

• The returned FDateTime is in UTC — if you display it to the user you will need to apply a local time offset manually, as FDateTime has no time zone metadata.
• Negative Unix timestamps (dates before 1970) may be passed but the result must still fall within FDateTime's valid range (year 1–9999). There is no overflow check in Shipping builds.
