It means Top Dead Centre
On a Nissan 1400 Bakkie the timing must be set at between 8 and 12 degrees before TDC for proper initial timing. This is constantly adjusted by the vehicle's computer during normal operation.
0 degrees TDC. However, there are several steps to set the timing. Refer to a repair manual specific to that vehicle for the exact procedure.
0 TDC base timing.
For a 1988 Nissan Pulsar with a 1.8-liter engine, the timing marks are typically located on the crankshaft pulley and the timing cover. The correct alignment is achieved when the timing mark on the crankshaft pulley is aligned with the timing mark on the timing cover at the top dead center (TDC) of the first cylinder. Ensure the engine is at TDC before making any adjustments to the timing. Refer to the owner's manual or a service manual for precise details specific to your vehicle.
The Top Dead Center (TDC) on a 1992 Cadillac DeVille V8 with a 4.9-liter engine refers to the position of the piston at the very top of its stroke in the cylinder. For this engine, TDC is typically used as a reference point for timing the ignition and configuring the engine's timing components. To locate TDC, you can manually rotate the crankshaft until the timing mark aligns with the pointer on the timing cover, or by using a TDC indicator tool.
On a 1992 Isuzu pickup with a 2.3L carbureted engine, the timing marks are typically located on the crankshaft pulley and the timing cover. The crankshaft pulley will have a notch or mark that aligns with a corresponding mark on the timing cover. To set the ignition timing, you usually align these marks when the engine is at the specified top dead center (TDC) for the number one cylinder. Consult the vehicle’s service manual for the exact TDC position and timing specifications.

the number one piston is on the left of you when facing the vehicle, it is the right side or passenger side and it must be at TDC for timing settings. (FENIX)
The timing is supposed to be 8 degrees before top dead center (tdc). But, when you first start it up it (the ecu) will advance the timing to 12 degreees before (tdc) for quicker easier starting, I'm guessing. When it warms up it should be 8 degrees before (tdc).
