rizzy

All in a tizzy over timestamps? rizzy is a UNIX filter that will convert UTC timestamps into the timestamp of your choosing.

Example

Before:

$ cat some.log.file
2021-09-17 17:28:07+0000 INFO Running on slurm - limited math CPU usage by a SLURM_CPUS_ON_NODE of 3
2021-09-17 17:30:12+0000 INFO Initializing Environment. Using Environment.V5_C_PROD

After:

$ cat some.log.file | rizzy --chi
2021-09-17T12:28:07-05:00 INFO Running on slurm - limited math CPU usage by a SLURM_CPUS_ON_NODE of 3
2021-09-17T12:30:12-05:00 INFO Initializing Environment. Using Environment.V5_C_PROD

Flags

Running rizzy --help gives more information, but basically:

• use --chi for Chicago and --nyc for New York
• for other zones use --zone ...
• To output in other formats than RFC3339 use --format
• To optionally treat big numbers encountered as nanos-since-epoch, use --convert-epoch-nanos

Building and running

• Grab rustup - either from the website or by sudo snap install rustup --classic.
• Install the stable rust version: rustup install stable
• Build the code with cargo build, or run with cargo run

Making a release

• Bump the version in Cargo.toml
• Run cargo build and cargo test to make sure everything's working and to ensure the Cargo.toml gets updated.
• Commit!
• Push and make sure all's well
• Tag the version with vXX.YY/ZZ
• Push the tag (git push --tags) which should kick things off automatically!
• Make sure all's well and then mark the release as current in GitHub (with some helpful explanation)
