AGameStateBase::GetServerWorldTimeSeconds

function Engine Blueprint Since 4.14

#include "GameFramework/GameStateBase.h"

Access: public Specifiers: virtualUFUNCTIONBlueprintCallable

Description

Returns an approximation of the server's current WorldTimeSeconds, synchronized across server and clients via periodic replication. Use this instead of GetWorld()->GetTimeSeconds() when you need a time value consistent across all machines.

Caveats & Gotchas

• The value is only as fresh as the last replication update. ServerWorldTimeSecondsUpdateFrequency (default ~5 seconds) controls how often it syncs. For sub-second precision (e.g., lag compensation), use a dedicated time-sync approach rather than relying on this.
• On the server, this returns the actual world time plus zero delta. On clients, it returns the replicated time plus a computed delta (ServerWorldTimeSecondsDelta), which smooths over network jitter using a rolling average — sudden network hitches can cause brief inaccuracies.
• Changed from float to double in UE 5.1 to support long-running sessions (float loses sub-second precision after ~4.5 hours). If you store the result in a float variable in older code, you'll silently lose precision — use double.

ENGINE_API virtual double GetServerWorldTimeSeconds() const;

Return Type

double

Example

Stamp an event with synchronized server time C++

void AMyActor::OnPickupCollected(APlayerController* Collector)
{
    if (HasAuthority())
    {
        AGameStateBase* GS = GetWorld()->GetGameState<AGameStateBase>();
        double ServerTime = GS ? GS->GetServerWorldTimeSeconds() : 0.0;
        UE_LOG(LogTemp, Log, TEXT("Pickup collected at server time: %f"), ServerTime);
        // Replicate this timestamp to clients for replay or UI display
    }
}
