TIME SYNC on TREZOR

I have been using the TREZOR (new) and receiving coins without any problem. However, the graphic interpretation is off by one day. This somewhat concerns me for the possibility of a time-sync error. It does not show as having been received on Tuesday (today) but Monday (yesterday). All else seems to be OK. Is this simply sloppy graphics, a transient error that will self-correct, or a worst-case scenario of some type of hack? I have had no problem with this storage unit. Aside from the graphic bar graph being off by one day, everything seems fine.
