Date, Time, Timezone

• date: A Gregorian calendar date (range: 0001-01-01 to 9999-12-31), independent of time zone.
• datetime: A Gregorian date and a time (range: 0001-01-01 00:00:00 to 9999-12-31 23:59:59.999999), as they might be displayed on a watch, independent of time zone. It includes the year, month, day, hour, minute, second, and subsecond. To represent an absolute point in time, use a timestamp.
• day: The day component of a date, datetime, or timestamp.
• hour: The hour component of a datetime or timestamp
• microsecond: The microsecond component of a datetime or timestamp
• minute: The minute component of a datetime or timestamp.
• month: The month component of a date, datetime, or timestamp.
• second: The second component of a datetime or timestamp
• timestamp: an absolute point in time (range: 0001-01-01 00:00:00 UTC to 9999-12-31 23:59:59.999999 UTC), independent of any time zone or convention such as daylight saving time (DST), with microsecond precision.
• timezone: A string that represents a timezone or UTC offset. For a reference of timezone strings, see the List of tz database time zones article on Wikipedia.
• year: The year component of a date, datetime, or timestamp.

Lambda Helper Function

A Lambda Helper function is a native function which accepts a reusable Lambda function as an argument along with one or more other inputs. Alternatively, the Lambda function could be written as an expression with the name each as follows:

1 each

This is useful when calling all instances of a repeated attribute in source data. Typically, the each will be referenced in a Lambda Helper Function that supplies more information regarding the variable.

Lambda functions include:

• Apply
• Filter
• Flatmap
• List
• Map
