Function parseTimestamp

Safely parses different timestamp formats into a standardized Date object

Handles multiple timestamp formats that may exist in the dataset:

  • ISO 8601 date strings
  • Unix timestamp milliseconds as strings
  • Other date string formats

Returns null for invalid or empty timestamps to enable safe optional chaining.
