# Start Time

The following options are available for setting the start time:

1. Automatic
2. Relative
3. Absolute

## Automatic

With *Automatic*, the current timestamp is used. Depending on the configured start database, this is adjusted accordingly. For example, with database *DAYS* the current day, with database *MONTHS* the current month, and with database *YEARS* the current year is used.

## Relative

The *Relative* selection always refers to the current time. The following settings can be made:

* Offset
* Duration
* Reference

### Offset

The offset shifts the end of the time range forward by the configured offset. The offset can be either a negative or a positive value.

#### Examples:

**We want to have values from the last three days depending on the current timestamp. The current day should not be included!**

*Current timestamp 06.01.2021*

*Offset: -1 day(s)*

*Duration: 3 day(s)*

*Start Database: Days*

*Result: 03.01.2021 00:00:00 - 05.01.2021 23:59:59*

**We want to have values from the last three days plus tomorrow depending on the current timestamp.**

*Current timestamp 06.01.2021*

*Offset: +1 day(s)*

*Duration: 4 day(s)*

*Start Database: Days*

*Result: 04.01.2021 00:00:00 - 07.01.2021 23:59:59*

### Duration

The duration determines the exact time range that the object should represent. Only a positive value can be specified.

#### Example:

**We want to have values from the last three months depending on the current timestamp.**

*Current timestamp 06.01.2021*

*Offset: 0*

*Duration: 3 month(s)*

*Start Database: Days*

*Result: 01.11.2020 00:00:00 - 31.01.2021 23:59:59*

### Reference

The reference defines the so-called start time point (start time grid) from which the offset and duration are calculated.

#### Examples:

**We want values from the current month. It should start from the 3rd of the current month.**

*Current timestamp 06.01.2021*

*Offset: 2 day(s)*

*Duration: 1 month(s)*

*Reference: Month(s)*

*Start Database: Days*

*Result: 03.01.2021 00:00:00 - 03.02.2021 00:00:00*

**We want values from the current year. It should start from March 1st of the current year.**

*Current timestamp 06.01.2021*

*Offset: 2 month(s)*

*Duration: 1 year(s)*

*Reference: Year(s)*

*Start Database: Days*

*Result: 01.03.2021 00:00:00 - 01.03.2022 00:00:00*

## Absolute

The *Absolute* setting is defined depending on the object type either via start and end timestamps or only via one timestamp.
