Parse Timestamp directive

The PARSE-TIMESTAMP directive parses column values representing unix timestamp as date.

Syntax

Usage Notes

The PARSE-TIMESTAMP directive will parse a column representing Unix timestamp. The column type can be string or long. long or string as date objects. The directive also has optional parameter timeunit which can be seconds, milliseconds, or microseconds. The default timeunit is milliseconds. If the column is null or has already been parsed as a date, applying this directive is a no-op. The column to be parsed as a date should be of type string.

Examples

if the column has unix timestamp 1536332271894 or "1536332271894", then after applying this directive, the column value represents date equivalent of UTC: Friday, September 7, 2018 2:57:51.894 PM.
