Examples with Timestamp com.google.firebase.Timestamp used on opensource projects

Example 26 with Timestamp

use of com.google.firebase.Timestamp in project firebase-android-sdk by firebase.

the class ServerTimestampTest method verifyTimestampsAreResolved.

/**
 * Verifies a snapshot containing setData but with resolved server timestamps.
 */
private void verifyTimestampsAreResolved(DocumentSnapshot snapshot) {
    assertTrue(snapshot.exists());
    Timestamp when = snapshot.getTimestamp("when");
    assertNotNull(when);
    // Tolerate up to 48*60*60 seconds of clock skew between client and server. This should be more
    // than enough to compensate for timezone issues (even after taking daylight saving into
    // account) and should allow local clocks to deviate from true time slightly and still pass the
    // test.
    int deltaSec = 48 * 60 * 60;
    Timestamp now = Timestamp.now();
    assertTrue("resolved timestamp (" + when + ") should be within " + deltaSec + "s of now (" + now + ")", Math.abs(when.getSeconds() - now.getSeconds()) < deltaSec);
    // Validate the rest of the document.
    assertEquals(expectedDataWithTimestamp(when), snapshot.getData());
}

Example 27 with Timestamp

use of com.google.firebase.Timestamp in project firebase-android-sdk by firebase.
