# Convert a date into another format with a TypoScript UserFunc

Powermail delivers a userFunc that could be used from administrators to convert date formats with TypoScript.
This userFunc is not needed for the normal work of the extension.
It is just an add-on for your special needs.


Example Use-Case:

* Powermail with a date field is in use
* After submit the date should be stored in a third-party-table (e.g. tx_ext_domain_model_table.endtime or tt_content.endtime)
* The problem is, if someone would get the POST param from date field, it will be a readable string like "2015-12-31" but a timestamp is needed

```
# Convert 31.12.2015 to 2015-12-31
lib.test = USER
lib.test {
    userFunc = In2code\Powermail\UserFunc\DateConverter->convert
    includeLibs = EXT:powermail/Classes/UserFunc/DateConverter.php

    input = TEXT
    input.value = 31.12.2015

    inputFormat = TEXT
    inputFormat.value = d.m.Y

    outputFormat = TEXT
    outputFormat.value = Y-m-d
}
```

```
# Convert 2015-12-31 into 1451516400
lib.test = USER
lib.test {
    userFunc = In2code\Powermail\UserFunc\DateConverter->convert

    inputFormat = TEXT
    inputFormat.value = Y-m-d

    outputFormat = TEXT
    outputFormat.value = U
}
