# DateFormatCSVs

A list of date formats that HPE Content Component must be able to read from documents. Separate multiple date formats with commas. There must be no space before or after a comma.

You can use the following values:

- `AUTNDATE`. The HPE date format (1 to a maximum of 10 digits). This format covers the epoch range (1 January 1970 to 19 January 2038) to a resolution of one second, and dates between 30 October 1093 BC and 26 October 3058 to a resolution of one minute. Dates outside this range are stored with values that allow HPE Content Component to sort them correctly. You can convert another date to its `AUTNDATE` representation by using the DateConvert action.

  Note: HPE recommends that you use one of the verbose date formats if you want to use dates outside the normal epoch.

- a string that contains one or more of the following:

  `YY` | Year (two digits). For example, 99, 00, 01, and so on.
  `YYYY` | Year (four digits). For example, 1999, 2000, 2001, and so on.
  `#YY+` | Year (two or four digits). If you provide two digits, it uses the `YY` format. If you provide four digits, it uses the `YYYY` format. For example, it interprets `07` as `2007 AD` and `1007` as `1007 AD`.
  `#Y` | Year (one to a maximum of 16 digits), optionally followed by `AD` or `BC`. An apostrophe (`'`) immediately before the year denotes a truncated year. For example, `2008`, `'97` (interpreted as `1997`), `97` (interpreted as `97 AD`), `'08` (interpreted as `2008`), `2008 AD`, and `200 BC`. A truncated year with a BC identifier is not valid (`'08 BC`).
  `#FULLYEAR` | Year (one to a maximum of 16 digits). For example, `8`, `98`, `108`, `2008`, each of which is taken literally. The year is taken relative to the common EPOCH (0 AD).
  `#YEARSIGN` | A plus (+) or minus (-) sign at the start of your date. A plus sign (+) represents AD/CE years, and a minus sign (-) represents BC/BCE years. If you specify the `#YEARSIGN` option as part of a date format, the plus or minus sign is not optional.
  `#ADBC` | Time period. For example, `AD`, `CE`, `BC`, `BCE`, or any predefined list of EPOCH indicators. Typically, the year specified in the above formats is interpreted as untruncated and relative to the EPOCH. For example, 84 AD is interpreted as 1984 AD, and 84 BC is interpreted as 84 BC. The only exception to this is when you use both `#YY+` and `#ADBC`. In this case, the format is interpreted as untruncated, even if the year was set to truncated by `#YY+`. For example, 99 AD is interpreted as the year 99 AD. HPE recommends that you use only `YY`, `YYYY`, or `#FULLYEAR` with `#ADBC`.
  `LONGMONTH` | A long month, for example, `January`, `February`, and so on.
  `SHORTMONTH` | A short month, for example, `Jan`, `Feb`, and so on.
  `MM` | Month (two digits). For example,`01`, `10`, `12`, and so on.
  `M+` | Month (one or two digits). For example, `1`,`2`,`3`,`10`, and so on.
  `DD` | Day (two digits). For example, `01`, `02`, `03`, `12`, `23`, and so on.
  `D+` | Day (one or two digits). For example, `1`, `2`, `12`, `13`, `31`, and so on.
  `LONGDAY` | Two digits with a postfix. For example, `1st`, `2nd`, and so on.
  `HH` | Hour (two digits). For example, `01`, `12`, `13`, and so on.
  `H+` | Hour (one or two digits).
  `NN` | Minute (two digits).
  `N+` | Minute (one or two digits).
  `SS` | Second (two digits).
  `S+` | Second (one or two digits).
  `F` | Milliseconds (one digit).
  `FF` | Milliseconds (two digits).
  `FFF` | Milliseconds (three digits).
  `F+` | Milliseconds (one to three digits).
  `ZZZ` | Time zone, for example, `GMT`, `EST`, `PST`, and so on.
  `ZZZZZ` | Time difference (one to nine digits). For example, `+04` denotes four hours ahead of UTC. Other examples include `+4`, `+04`, `+0400`, `+0400 MSD` (the string `MSD` is ignored). A further example is `+030`. In this case the time difference is interpreted as 30 minutes.
  `#PM` | An `AM` or `PM` indicator (two characters). For example, `2001/09/09 02:46:40 PM`.
  `#S` | A space.

Notes

- Specify formats in order of length (starting with the longest). HPE Content Component matches format strings in the order in which you list them. If you list a shorter format first, HPE Content Component might match against an incorrect format, for example, matching `19/10/2002` as `DD/MM/YY` and indexing the document with the date `19/10/20`.

- Separate multiple formats with commas. There must be no space before or after a comma. To specify a format that contains a space, put the format in quotation marks.

- When the document field contains a partial date, HPE Content Component assigns the document a metadata field with a full date.

  - If the day is not specified, the date is the first day of the specified month.

  - If neither the day or month are specified, the date is the first of January in the specified year.

Partial dates are indexed only if they are listed in `DateFormatCSVs`.

Type: | String
Default: | `YYYY/MM/DD`
Required: | No
Configuration Section: | Server
Example: |
    DateFormatCSVs=D+/SHORTMONTH/YYYY,DDMMYY
In this example, only document dates with the format `D+/SHORTMONTH/YYYY` (for example, `2/Jan/2001`) or `DDMMYY` (for example, `020101`) can be indexed with a date.
    DateFormatCSVs="D+SHORTMONTH YYYY","Date: D+ LONGMONTH, YYYY"
In this example, only document dates with the format `D+ SHORTMONTH YYYY` (for example, `2 Jan 2001`) or `Date: D+ LONGMONTH, YYYY` (for example, `Date: 2 January, 2001`) can be indexed with a date.
    DateFormatCSVs=LONGMONTH/D+/#Y H+:N+:S+
In this example, only document dates with the format `LONGMONTH/D+/#Y H+:N+:S+` (for example, `September/9/2001 AD 2:46:40` or `September/9/2001 2:46:40` or `September/9/'01 2:46:40` or `September/9/'01 AD 2:46:40`) can be indexed with a date.
    DateFormatCSVs=LONGMONTH/D+/#FULLYEAR #ADBC H+:N+:S+
In this example, only document dates with the format `LONGMONTH/D+/#FULLYEAR #ADBC H+:N+:S+` (for example, `September/9/8 AD 2:46:40` or `September/9/2008 AD 2:46:40` or `September/9/'01 2:46:40` or `September/9/'01 AD 2:46:40`) can be indexed with a date.
    DateFormatCSVs=D+ LONGMONTH YYYY HH:NN:SS ZZZZZ
In this example, only document dates with the format `D+ LONGMONTH YYYY HH:NN:SS ZZZZZ` (for example, `17 May 2003 10:41:07 -0400`) can be indexed with a date.
