- Use UNIX (or DOS) pipes to pipe the stdout of any command through gnomon:
`{{npm test}} | gnomon`
- Show number of seconds since the start of the process:
`{{npm test}} | gnomon --type=elapsed-total`
- Show an absolute timestamp in UTC:
`{{npm test}} | gnomon --type=absolute`
- Set a high threshold of 0.5 seconds for the elapsed time; exceeding which the timestamp will be colored bright red:
`{{npm test}} | gnomon --high {{0.5}}`
- Set a medium threshold of 0.2 seconds (Timestamp will be colored bright yellow):
`{{npm test}} | gnomon --medium {{0.2}}`
