flash files creation dates changed after daylight savings time went away

Seen in both CATOS and IOS, file creation dates

changed to 1 hour earlier on all files in either flash cards or built-in bootflash when

doing a dir <device>:

Anyone know why?

I do not know the answer authoritatively. So this is my understanding not necessarily a fact. I believe that time and time and date stamps are really recorded in UTC (Coordinated Universal Time or GMT) and are translated into local time by show commands, the syslog process etc. So the time and date recorded for the file in flash were rendered as one time when we were on daylight savings time and are rendered one hour earlier when we move into standard time. They both are based on the same underlying UTC.

Your explanation certainly makes sense. The issue came to light when our rancid system did a checkpoint on the configs to detect changes,

so we get false positives. Not a big problem.

thanks for the info.
