I want to know this because I died really far away and I am stressing that the items will despawn. My world tick speed is 1.

From the wiki:
Items despawn after 6000 game ticks (5 minutes) of being in a loaded chunk. If two item stacks merge, the timer is set to the item that has more time remaining. The 5-minute timer is paused when the chunk is unloaded.
