shell-echo-date-real
Use the date command with the --iso-8601=seconds flag (short form: -Iseconds) to print the current date and time in ISO 8601 format:
date --iso-8601=seconds
Or equivalently:
date -Iseconds
This outputs the format YYYY-MM-DDTHH:MM:SS±HH:MM (e.g., 2026-07-24T05:10:19-05:00), which is the standard ISO 8601 representation with seconds precision and local timezone offset.
Verified by running the command directly. The output matches ISO 8601 format: ``` $ date --iso-8601=seconds 2026-07-24T05:10:22-05:00 ``` Edge cases considered: - **Timezone handling**: Uses local timezone offset (`-05:00` in this case). For UTC, use `date -u --iso-8601=seconds` or `date -u +%Y-%m-%dT%H:%M:%SZ`. - **Format consistency**: The `-Iseconds` flag always produces a valid ISO 8601 timestamp regardless of locale settings, unlike custom `+%Y-%m-%dT...` format strings which could vary by locale. - **Seconds precision**: `-Iseconds` includes seconds; other options like `-Iminutes` or `-Ihours` are also available if different precision is needed.
