file creation dates with root.ls

Other Hardware Storage

Here is what I get from Cardinfo:

Files found on the card (name, date and size in bytes):
TEST.TXT 2000-01-01 01:00:00 36
LOGGER00.CSV 2000-01-01 01:00:00 0
LOGGER01.CSV 2000-01-01 01:00:00 1917
LOGGER02.CSV 2000-01-01 01:00:00 461
LOGGER03.CSV 2000-01-01 01:00:00 197
LOGGER04.CSV 2000-01-01 01:00:00 2295
LOGGER05.CSV 2000-01-01 01:00:00 93
LOGGER06.CSV 2000-01-01 01:00:00 1499

Can somebody explain why the actual creation (last modification?) dates aren't shown correctly? Thanks.

Files will only be time/date stamped if you have a RTC, RTC library, and time/date callback functions for SdFat, the base library for SD.h.
