git command to show all (lightweight) tags creation dates

I found in this link a solution that fits my needs:

git log --tags --simplify-by-decoration --pretty="format:%ai %d"

I've put that command in an alias in my ~/.alias, so now everytime I run gitshowtagbydate I get what I needed.

git date tags

The git tag -l shows a list of all tags. The --format argument can be used to define a custom output. For example:

git tag -l --format='%(refname)   %(taggerdate)'

Update, based on the comments below:

 git tag -l --sort=-creatordate --format='%(creatordate:short):  %(refname:short)'
