> Key: SPARK-57740
> URL: https://issues.apache.org/jira/browse/SPARK-57740
> Project: Spark

> *What is the issue?*
> The four {{unix_*}} epoch-unit functions form a family. {{unix_nanos}} (added in SPARK-57579) correctly lists all three siblings in its {{See Also}} section. However, none of the three siblings were updated to link back to {{{}unix_nanos{}}}, breaking discoverability of the family from the existing functions.
> Current {{See Also}} sections:
> ||Function||Links to||
> |{{unix_micros}}|{{{}unix_date{}}}, {{{}unix_seconds{}}}, {{{}unix_millis{}}}, {{timestamp_micros}} — *missing {{unix_nanos}}*|
> |{{unix_millis}}|{{{}unix_date{}}}, {{{}unix_seconds{}}}, {{{}unix_micros{}}}, {{timestamp_millis}} — *missing {{unix_nanos}}*|
> |{{unix_seconds}}|{{{}unix_date{}}}, {{{}unix_millis{}}}, {{{}unix_micros{}}}, {{{}from_unixtime{}}}, {{timestamp_seconds}} — *missing {{unix_nanos}}*|
> |{{unix_nanos}}|{{{}unix_date{}}}, {{{}unix_seconds{}}}, {{{}unix_millis{}}}, {{unix_micros}} — complete|
> ----
> *How to reproduce*
> Read the {{See Also}} section of {{{}pyspark.sql.functions.unix_micros{}}}, {{{}unix_millis{}}}, or {{unix_seconds}} in the PySpark docs or via {{{}help(){}}}. None of them mention {{{}unix_nanos{}}}.
> ----
> *Actual behavior*
> {{help(pyspark.sql.functions.unix_micros)
> # See Also section lists: unix_date, unix_seconds, unix_millis, timestamp_micros
> # unix_nanos is absent}}
> ----
> *Expected behavior*
> {{help(pyspark.sql.functions.unix_micros)
> # See Also section lists: unix_date, unix_seconds, unix_millis, timestamp_micros, unix_nanos}}
> Same for {{unix_millis}} and {{{}unix_seconds{}}}.
> ----
> *Proposed fix*
> Add {{{}:meth:\{}}}pyspark.sql.functions.unix_nanos`{{{}to the{}}}See Also{{{}sections of{}}}unix_micros{{{}, {}}}unix_millis{{{}, and {}}}unix_seconds{{{}in{}}}python/pyspark/sql/functions/builtin.py`. Three lines total.
