( value )

Description

The ToMillis function converts a value to the number of milliseconds since Unix epoch (midnight, January 1, 1970), if possible.

Attempting to convert a value to a number of milliseconds which has no numeric representation results in an "invalid argument" error.

Parameters

Parameter Type Definition and Requirements

value

Any

Returns

Examples

The following query calls ToMillis twice:

  1. To convert 1 second after Unix epoch into milliseconds.

  2. To convert the current transaction time into milliseconds.
