Time Synchronization with data collected from multiple sensors

Hi, I am new to ROS and have a question about time synchronization.

I am trying to synchronize Velodyne Lidar data with other data collected from multiple sensors (all float data).

I created a node to receive the multiple data and each data is a single float number.

As Time Synchronizer in ros takes specific data type such as PointCloud2 and Image with timestamp header, it doesn't take

std_msgs type. ( Initially, I read the multiple data in std_msgs in a single node but it can't synchronize due to the data type)

I was wondering how to synchronize those multiple data. Can I still use PointCloud2 or Image without creating custom message?

Thank you!
