strongswan-plugin-systime-fix-dbgsym 5.1.2-0ubuntu7 (ppc64el binary) in ubuntu xenial

 The strongSwan VPN suite uses the native IPsec stack in the standard
 Linux kernel. It supports both the IKEv1 and IKEv2 protocols.
 .
 The systime-fix plugin for strongSwan is designed for embedded systems that
 don't have a valid system time just after boot. It detects if the system time
 is incorrect and disables certificate lifetime validation during this period.
 This allows the device to establish tunnels, even if the system time is out of
 sync, and for example connect to an NTP server.
 .
 Once the system time gets corrected, the plugin can detect it and verify the
 lifetimes of all certificates used for active tunnels. If any certificate in
 the trust-chain is not valid for the given system time, the tunnel gets either
 closed or reestablished.
