| The image when you use `ko` to create won't set the create timestamp in the image attribute. If you want to set the create timestamp, just execute SOURCE_DATE_EPOCH=`date +%s` on your environment before use `ko`. | |
| In order to support [reproducible builds](https://reproducible-builds.org), `ko` doesn't embed timestamps in the images it produces by default; however, `ko` does respect the [`SOURCE_DATE_EPOCH`](https://reproducible-builds.org/docs/source-date-epoch/) environment variable. | |
| For example, you can set this to the current timestamp by executing: | |
| export SOURCE_DATE_EPOCH=`date +%s | |
| or to the latest git commit's timestamp with: | |
| export SOURCE_DATE_EPOCH=$(git log -1 --format='%ct') |
