Bookworm - cron?

[Steve Sobol]

Crazy question:

My VPS provider just started offering bookworm images. So when I set up 
a new server yesterday, I installed bookworm.

Part of my standard procedure for setting up new VMs involves editing 
root's crontab.

But cron isn't installed.

What am I expected to use instead? (I assume that I *could* install 
cron, but there must be a reason it's not installed by default anymore, 
right?)

Thanks :)
