util.Datetime.toSecondsSinceEpoch()
util.Datetime.toSecondsSinceEpoch() converts a DATETIME value to a FLOAT value showing the number of seconds since Unix epoch.
Syntax
util.Datetime.toSecondsSinceEpoch(datetime)
Parameters
|
datetime |
a DATETIME value for that you want to get number of seconds since Unix Epoch |
Usage and examples
util.Datetime.toSecondsSinceEpoch() takes a DATETIME value and returns a FLOAT value showing the number of seconds since Unix epoch (1970-01-01 00:00:00 GMT).
Unix epoch is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds.
The resulting value is a whole number if the source is a DATETIME YEAR TO SECOND, or a floating-point number if the source is a DATETIME YEAR TO FRACTION(N) (this is so in order to include the fractional part).
