Define any timestamp format that does not appear in the list of defined formats. Health Log Analytics must be able to read timestamps of any format contained
in your log files.

## Before you begin

Role required: evt_mgmt_admin

## Procedure

1. Navigate to AllHealth Log AnalyticsData InputTimestamp Formats.
2. To determine whether your timestamp format matches a predefined format in the system, do the following:
   1. Select Find format.
   2. Enter a sample of your timestamp.
   3. Select Find format.

   {#hla-timestamp-formats-add__substeps_wyk_2ns_h4b}  
   If the sample matches an existing format, the system provides its ID.
3. If your timestamp sample doesn't match an existing format, then manually define your custom format and add it to the available timestamp formats.
   1. On the Timestamp Formats page, select New.
   2. On the form, fill in the fields.  
      {#hla-timestamp-formats-add__table_jdl_nmt_2pb__entry__2}

      | Field | Description |
      |-|-|
      | ID | ID of the timestamp format. This value is selected automatically. |
      | Format | Valid timestamp format. For example, dd-MMM-yyyy, HH:mm. Note: Health Log Analytics uses the [Java 8 API](https://docs.oracle.com/javase/8/docs/api/java/time/format/DateTimeFormatter.html) for timestamp syntax. |
      | Sample | Example of the timestamp format. For example, 03-May-2018, 10:20. |
      | Description | Description of the timestamp format. |
      [Table 1. Timestamp format form]

      {#hla-timestamp-formats-add__table_jdl_nmt_2pb}
   {#hla-timestamp-formats-add__substeps_jvk_mns_h4b}
4. Select Submit.

## Result

The system validates the timestamp format and adds it to the list of available timestamps.
