# Date-Time-Datetime

The utilization of the three date and time types necessitates specific guidelines for determining when they should be assigned a dedicated value through the 'Default value' field in the Metadata menu.

An incorrect setting may result in an 'Invalid Date' error.

{% hint style="warning" %}
It is crucial that the Pre-Resolve checkbox for the designated metadata value is enabled.

### DATE

Setting metadata for a date is straightforward.

For example: Date - 2024-09-02

* Default value: +0
  * Today -> 2024-09-02<br>
* Default value: +1
  * Tomorrow -> 2024-09-03<br>
* Default value: -1
  * Yesterday -> 2024-09-01<br>
* Default value: +10
  * -> 2024-09-12

In addition to using the symbols + or - with an integer for inputting dates, you can also use the YYYY-MM-DD pattern or the wildcards [{date.year}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-year-1.md)-[{date.month}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-month-1.md)-[{date.day}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-day-1.md).

The input dialogue for configuring or modifying the metadata field appears as follows:

### TIME

Setting the time can be achieved by inputting the time in the following pattern: HH:mm or by using the wildcards [{time.hour}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/time-hour.md):[{time.minute}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/time-minute.md).

Please note that seconds cannot be used with this metadata type.

For example: current time - 12:23

* Default value: {time.hour}:{time.minute}
  * -> 12:23

### DATETIME

Datetime is a combination of date and time. Setting the metadata can be done manually by using a string with this pattern: YYYY-MM-DD HH:mm

It is possible to set this as well with dedicated wildcards:

[{date.year}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-year-1.md)-[{date.month}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-month-1.md)-[{date.day}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-day-1.md) [{time.hour}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/time-hour.md):[{time.minute}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/time-minute.md)

For example: current date & time - 2024-01-09 12:23

* Default value: {date.year}-{date.month}-{date.day} {time.hour}:{time.minute}
  * -> 2024-01-09 12:23

It is possible to use contextual date wildcards as well, for further information refer to

* [{date.year.?}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-year.md)
* [{date.month.?}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-month.md)
* [{date.day.?}](/helmut4-releases/v4.8.0/helmut4-components/streamdesigner/wildcards/date-and-time-21/date-day.md)

{% hint style="info" %}
Please ensure strict adherence to the pre-defined syntax when assigning a default value.
{% endhint %}
