#### Time

| **Key name** | **Requirement level** | **Data type** | **Description** |
| --------------- | --------------------- | ------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| TimeZero | REQUIRED | [string][] | Time zero to which all scan and/or blood measurements have been adjusted to, in the unit "hh:mm:ss". This should be equal to `InjectionStart` or `ScanStart`. |
| ScanStart | REQUIRED | [number][] | Time of start of scan with respect to `TimeZero` in the default unit seconds. |
| InjectionStart | REQUIRED | [number][] | Time of start of injection with respect to `TimeZero` in the default unit seconds. This corresponds to DICOM Tag 0018, 1042 `Contrast/Bolus Start Time` converted to seconds relative to `TimeZero`. |
| FrameTimesStart | REQUIRED | [array][] of [numbers][] | Start times for all frames relative to `TimeZero` in default unit seconds. |
| FrameDuration | REQUIRED | [array][] of [numbers][] | Time duration of each frame in default unit seconds. This corresponds to DICOM Tag 0018, 1242 `Actual Frame Duration` converted to seconds. |
| ScanDate | RECOMMENDED | [string][] | Date of scan in the default unit `"YYYY-MM-DD[Z]"`, with the Z indicator being optional for indicating UTC timezone (see [Units](../02-common-principles.md#units)). |
| InjectionEnd | RECOMMENDED | [number][] | Time of end of injection with respect to `TimeZero` in the default unit seconds. |

| ScanDate | [DEPRECATED][deprecated] | [string][] | Date of scan in the format `"YYYY-MM-DD[Z]"`. This field is DEPRECATED, and this metadata SHOULD be recorded in the `acq_time` column of the corresponding [Scans file](../03-modality-agnostic-files.md#scans-file). |

We refer to the common principles for the standards for describing dates and timestamps, including possibilities for anonymization (see the [units section](../02-common-principles.md#units)).
