On the "Backups" tab in the Linode Manager, each automatic backup has a start date/time and an end date/time, but no time zone. The "Backup Window" field up above indicates GMT-5, but the window I've chosen is 0200-0400, whereas all of my backups run shortly after 0100.

So I'm wondering if there's a timezone discrepancy here, and more specifically what the timezone is of the timestamps in the "Backup History" report. Anyone know for sure?

My daily automatic backups seem to finish at a fairly consistent time every day and I'm going to schedule a resize via API for a low-traffic time, but I'd like to be certain that the resize will happen after the daily automatic backup. Can't quite be certain without knowing what that timezone is.

Turns out it's the timezone you have set in your login profile. Mine was GMT-6 and I tried switching it to GMT-5 and then refreshing the Backup History page. The times then matched up with my chosen backup window. Question answered!
