Batch Unix Timestamp Converter: Many Epochs at Once

Many Unix timestamps at once (ISO, UTC, RFC 2822, relative), with row and byte caps.

Timestamps
one per line
Rules this tool follows
  • Same parser as the single-timestamp converter. Seconds/milliseconds semantics and the auto-mode ambiguity flag cannot drift between the two tools.
  • Caps: 500 rows and 128 KB per run, refused whole when over: split the batch instead.
  • Relative times are computed against the moment the batch was parsed, in this tab; ISO/UTC strings are exact.
  • Bad rows report by line number and never poison good ones. "#" lines are comments.
