The string format complies to ISO8601 day format
from date(1)
-I[FMT], --iso-8601[=FMT]
output date/time in ISO 8601 format. FMT='date' for date only (the
default),
'hours', 'minutes', 'seconds', or 'ns' for date and time to the
indicated preci-
sion. Example: 2006-08-14T02:34:56-06:00
so date -Im can do the same.
