How to use the rosbag.TimeUtil.areSame function in rosbag

function itemsMatchingStamp(
  stamp: Time,
  itemsByPath: MessageHistoryItemsByPath,
  getHeaderStamp?: (itemMessage: Message) => ?Time
): ?MessageHistoryItemsByPath {
  const synchronizedItemsByPath = {};
  for (const path in itemsByPath) {
    let found = false;
    for (const item of itemsByPath[path]) {
      const thisStamp = getHeaderStamp
        ? getHeaderStamp(item.message)
        : get(item.message, ["message", "header", "stamp"]);
      if (thisStamp && TimeUtil.areSame(stamp, thisStamp)) {
        found = true;
        synchronizedItemsByPath[path] = [item];
        break;
      }
    }
    if (!found) {
      return null;
    }
  }
  return synchronizedItemsByPath;
}

hasLifetime() {
    return !TimeUtil.areSame(this.getLifetime(), ZERO_TIME);
  }
}

const matchingMessage = messages[topic].find(({ message }) => {
      const thisStamp = get(message, ["header", "stamp"]);
      return thisStamp && TimeUtil.areSame(stamp, thisStamp);
    });
    if (!matchingMessage) {
