By 15 May 2013 at 15:29:10 (Hong Kong Time), the Sub CA "Hongkong Post e-Cert CA 1" will expire, and all certificates previously issued by it will expire before 15 May 2013.

The Sub CA "Hongkong Post e-Cert CA 1" will issue the last full CRL and partitioned CRLs at 14:15 on 15 May 2013 (Hong Kong Time) at the following links and no further update will be provided in future:
