Time unit 86400 meaning in the yaml file

[abdulrehman565]

I have two questions:

1. In the data_catalog.yaml file, What does time:86400 mean in unit add?
   hirps_global:
   crs: 4326
   data_type: RasterDataset
   driver: netcdf
   meta:
   category: meteo
   paper_doi: 10.3133/ds832
   paper_ref: Funk et al (2014)

   source_url: https://www.chc.ucsb.edu/data/chirps
   source_version: v2.0
   path: chirps_global.nc
   unit_add:
   time: 86400
   (the bold part)

2. I am currently using era5_land precipitation data. And this product accumulates all the precipitation values in the 0th hour so I'm using only the 0th hour data for a number of years. When I ran the model, the result came out to be wrong. How to use the precipitation netcdf file for 0th hour only?

I think 86400 is converting 1 day time step to seconds (1 * 24* 60*60).
