URL: https://github.com/apache/hudi/issues/17365#issuecomment-4892569201

   This issue was reviewed as part of the JIRA-migrated backlog triage and 
reproduced/validated on the spark-hudi container (Spark 3.4).
   
   Findings: the timestamp-based partitioning defect reproduces on 0.15.0 and 
is fixed on current Hudi. Test: CustomKeyGenerator with 
partitionpath.field=ts:timestamp,segment:simple (SCALAR seconds, yyyyMM).
   - On 0.15.0, reading back returns the partition-derived value in the ts 
column (ts=[202312,202401,202402]) instead of the original epochs - the 
reported 'field replaced with partition value' bug.
   - On 1.2.0 the ts column returns the original epochs 
[1701443427,1704121827,1706800227] - fixed. (delete_partition worked correctly 
on both in a single-partition-drop check.)
   
   The fix was targeted at 0.15.1, which was never released (0.15.x is EOL - 
releases go 0.15.0 -> 1.0.0 -> 1.2.0), and 1.0+ already works, so no supported 
version still exhibits this and there is no backport target.
   
   Closing as fixed on supported versions.
