# DatetimeMetricType

`data class DatetimeMetricType : `[`CommonMetricData`](../-common-metric-data/index.md) [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/src/main/java/mozilla/components/service/glean/metrics/DatetimeMetricType.kt#L21)

This implements the developer facing API for recording datetime metrics.

Instances of this class type are automatically generated by the parsers at build time,
allowing developers to record values that were previously registered in the metrics.yaml file.

### Functions

| Name | Summary |
|---|---|
| [set](set.md) | `fun set(value: `[`Date`](https://developer.android.com/reference/java/util/Date.html)` = Date()): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html)<br>Set a datetime value, truncating it to the metric's resolution. |
| [testGetValue](test-get-value.md) | `fun testGetValue(pingName: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)` = getStorageNames().first()): `[`Date`](https://developer.android.com/reference/java/util/Date.html)<br>Returns the stored value for testing purposes only. This function will attempt to await the last task (if any) writing to the the metric's storage engine before returning a value. |
| [testGetValueAsString](test-get-value-as-string.md) | `fun testGetValueAsString(pingName: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)` = getStorageNames().first()): `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)<br>Returns the string representation of the stored value for testing purposes only. This function will attempt to await the last task (if any) writing to the the metric's storage engine before returning a value. |
| [testHasValue](test-has-value.md) | `fun testHasValue(pingName: `[`String`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)` = getStorageNames().first()): `[`Boolean`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)<br>Tests whether a value is stored for the metric for testing purposes only. This function will attempt to await the last task (if any) writing to the the metric's storage engine before returning a value. |
