### Question:
NmeaMessageExactEarthTimestamp { public static boolean isExactEarthTimestamp(String line) { try { new NmeaMessageExactEarthTimestamp(line); return true; } catch (AisParseException e) { return false; } catch (NmeaMessageParseException e) { return false; } } NmeaMessageExactEarthTimestamp(String line); static boolean isExactEarthTimestamp(String line); long getTime(); String getFollowingSequenceChecksum();  }### Answer:
