# testGetValue

`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) [(source)](https://github.com/mozilla-mobile/android-components/blob/master/components/service/glean/src/main/java/mozilla/components/service/glean/private/DatetimeMetricType.kt#L131)

last task (if any) writing to the the metric's storage engine before returning a value.

care about checking that the timezone offset was set and sent correctly, use
[testGetValueAsString](test-get-value-as-string.md) and inspect the offset.

    to the either the first value in [defaultStorageDestinations](default-storage-destinations.md) or the first
    value in [sendInPings](send-in-pings.md)

### Exceptions
