	The Hefei Light Source II (HLS-II) is a vacuum ultravi-olet (VUV) synchrotron light source. A major upgrade of the light source was finished in 2014, and the timing system was rebuilt with event-system to meet synchroni-zation requirements of the machine. The new timing system provides about 100 output signals with various interfaces. The time resolution of this system is 9.8 ns for most devices and 9 ps for the electron gun and the injec-tion kickers. The measured jitter of the output signal is less than 27 ps (RMS). In order to improve the perfor-mance of light source, the top-off operation mode has been planned. As part of this plan, both the hardware and the software of the timing system are upgraded. By ob-taining real-time data of beam measurement of storage ring, the automatic selection of the bucket is implement-ed. With any designated bunch pattern, top-off injection is achieved, and the storage ring beam can be uniform filled well.
