Hi, I wrote up this short document in order to address a problem seen in certain devices that do not have good time at startup. The document proposes a DHCv4 option and DHCPv6 option to supply current time to a device. (there is also a proposed ND option for the same thing). I looked into using option 152 from Bulk Query but that is only 32 bit long, and it seems cleaner to just get a 64bit time_t option into DHC Comments please Olafur Begin forwarded message: > From: internet-drafts@ietf.org > Subject: New Version Notification for draft-ogud-dhc-udp-time-option-01.txt > Date: December 1, 2013 3:42:27 PM EST > To: Olafur Gudmundsson <ogud@ogud.com> > > > A new version of I-D, draft-ogud-dhc-udp-time-option-01.txt > has been successfully submitted by Olafur Gudmundsson and posted to the > IETF repository. > > Filename: draft-ogud-dhc-udp-time-option > Revision: 01 > Title: Providing Time over DHCP and ND for devices w/o reliable clock upon boot > Creation date: 2013-12-01 > Group: Individual Submission > Number of pages: 7 > URL: http://www.ietf.org/internet-drafts/draft-ogud-dhc-udp-time-option-01.txt > Status: http://datatracker.ietf.org/doc/draft-ogud-dhc-udp-time-option > Htmlized: http://tools.ietf.org/html/draft-ogud-dhc-udp-time-option-01 > Diff: http://www.ietf.org/rfcdiff?url2=draft-ogud-dhc-udp-time-option-01 > > Abstract: > Many small inexpensive computing devices like home routers, Rasberry > Pi etc. do not have a battery to allow clock chip to keep track of > time, thus the systems have no idea what the current time is upon > boot.
