 | <a name="error_InsertTimeNull">`InsertTimeNull`</a> | An INSERT or REPLACE query encountered a null timestamp in the `__time` field.<br /><br />This can happen due to using an expression like `TIME_PARSE(timestamp) AS __time` with a timestamp that cannot be parsed. ([`TIME_PARSE`](../querying/sql-scalar.md#date-and-time-functions) returns null when it cannot parse a timestamp.) In this case, try parsing your timestamps using a different function or pattern. Or, if your timestamps may genuinely be null, consider using [`COALESCE`](../querying/sql-scalar.md#other-scalar-functions) to provide a default value. One option is [`CURRENT_TIMESTAMP`](../querying/sql-scalar.md#date-and-time-functions), which represents the start time of the job.|
