# Add a timestamp format in Health Log Analytics

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 **All** > **Health Log Analytics** > **Data Input** > **Timestamp 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**.

    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.

<table id="table_jdl_nmt_2pb"><thead><tr><th>
