Overview

Adds a default timestamp to the event or parses timestamp fields, and converts it to ISO 8601 format, which can be used as event timestamp.

Option	Required	Type	Description
match	Conditionally	List	List of `key` and `patterns` where patterns is a list. The list of match can have exactly one `key` and `patterns`. There is no default value. This option cannot be defined at the same time as `from_time_received`. Include multiple date processors in your pipeline if both options should be used.
from_time_received	Conditionally	Boolean	A boolean that is used for adding default timestamp to event data from event metadata which is the time when source receives the event. Default value is `false`. This option cannot be defined at the same time as `match`. Include multiple date processors in your pipeline if both options should be used.
destination	No	String	Field to store the timestamp parsed by date processor. It can be used with both `match` and `from_time_received`. Default value is `@timestamp`.
source_timezone	No	String	Time zone used to parse dates. It is used in case the zone or offset cannot be extracted from the value. If the zone or offset are part of the value, then timezone is ignored. Find all the available timezones the list of database time zones in the TZ database name column.
destination_timezone	No	String	Timezone used for storing timestamp in `destination` field. The available timezone values are the same as `source_timestamp`.
locale	No	String	Locale is used for parsing dates. It's commonly used for parsing month names(`MMM`). It can have language, country and variant fields using IETF BCP 47 or String representation of Locale object. For example `en-US` for IETF BCP 47 and `en_US` for string representation of Locale. Full list of locale fields which includes language, country and variant can be found the language subtag registry. Default value is `Locale.ROOT`.
