+# update-gitea-ctimes
+
+A script to modify creation time flags in Gitea to match the oldest Git commit.
+
+This is helpful for ordering repositories chronologically by creation-time after a migration to Gitea (e.g. for [teafolio](https://code.ivysaur.me/teafolio)).
+
+Written in PHP
+
+## Usage
+
+```
+Usage: update-gitea-ctimes gitea.db path/to/repositories
+```
+
+Running the command will produce SQL on stdout that can be manually inspected before applying it to the live SQLite database.
