getFileCreationTime

public static org.joda.time.Instant getFileCreationTime(URI uri,
                                                        byte[] decoded)
                                                 throws SignedObjectUtil.NoTimeParsedException

Extract the creation time from an object. This does not yet follow the method described in https://datatracker.ietf.org/doc/draft-timbru-sidrops-publication-server-bcp/00/. It differs in that it uses the signing time for RPKI signed objects. This is a trade-off: * signing-time is more correct when multi-use EE certificates are present. * signing-time likely does not match the modification time of the CRL. This needs to be revisited in 2024.

Parameters:

uri - URL of the object

decoded - object bytes

Returns:

the file creation time of the object

Throws:

SignedObjectUtil.NoTimeParsedException - if creation time could not be extracted.
