Load time of TimeZones

I am trying to reduce the load time of my packages, and found that TimeZones.jl does not behave well:

julia> @time import TimeZones
  0.592166 seconds (362.80 k allocations: 25.915 MiB, 71.02% compilation time)

using Julia 1.9 on Linux.

Any idea why it is compiling so much while loading?
