In gamma-ray astronomy, the time structure of the shower front is crucial to improve the angular resolution of primaries for ground-based experiments. With its full coverage detection area, high time resolution and excellent spatial granularity, the ARGO-YBJ experiment offers a good opportunity to study in detail the temporal behavior of the gamma-ray shower fronts. In this work, by using the data recorded from 2008 January to 2012 October, we extracted a significant sample of gamma ray showers from the Crab Nebula direction. The time profiles of gamma-ray induced and cosmic-ray induced showers are measured and compared. Besides that, the intrinsic time structures of showers are studied.
