I have no idea about simple and elegant solution for setting clock :( My hwclock man page show me an example: hwclock --set --date="2011-08-14 16:45:05" I'll try to find some ready-to-use strptime-like function (e.g. in uClibc). Also there is no epoch handling. May be it's better to drop hwclock clock setting in the inital rtc support series? -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list [email protected] http://lists.infradead.org/mailman/listinfo/barebox
