Hmm, I suppose a solution could be to create a script that queries pool.ntp.org and stores it in /etc/hosts (or the dnsmasq config) as 'cached.pool.ntp.org' or similar, and then configure that as an NTP server. And then have the script run periodically, and also at image build time? -Toke --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBCAAGBQJTLtF5AAoJEENeEGz1+utPdQkH/jz0OjRrP4mnqTmuLCoo/qDC PcutmIdE7VCaisc4Oy8a6Tt9432PTtHPgqozB+21lRDQsFXukeEp6KSqGHnL4llY p+44PyCSbRx8ZuZrqF+mhTflCVIxyR0XpLwlHu7iSK7uBZCJX56fb1YK2tx13wo2 9ig79IkiIS6lMKd5CsGPgxCN9QpFcN1zxB36WGv1lYn17pt5YEsmE3fIrgh3RjsP gjdEQ0LsKcbGB/k+EBJUV8JCodA9UI09tXuUqFVEL796t4qTyAtUcCJOgo3a9NHY DHw7a+nTFkj0hwhRoUmZVssCKHlYwjOZuWdX45lVOaQ9qXBpAbmmrHj/QDqOwVc= =EzNl -----END PGP SIGNATURE----- --=-=-=--
