Upgrading package “tzdata” wants me to remove 221(!) packages 12.04 LTS

Question

I had a fresh install of Ubuntu 12.04 LTS 64-bit. After a month or so i updated the packages (apt-get upgrade -y). All packages suceed except for tzdata. This one has been kept pack.

As i tried to upgrade it manually (apt-get install tzdata), I've seen that it needs to remove 221 packages to upgrade. The packages which will be removed are some standard system libs as far as i understand. If I upgrade, will the system be crashed

sudo apt-get install tzdata
