Public bug reported:
expect
du --time --time-style=+%s theFile
to give modification time of theFile expressed as seconds since the epoch.
Comparison to "date" shows that du is reporting the time wrongly.
This script:
echo "my time and time zone:" $(date)
touch timestampTest
echo "date says: " $(date -r timestampTest +%s)
echo "du says:" $(du --time --time-style=+%s timestampTest)
has this output:
my time and time zone: Fri 26 Aug 10:12:38 BST 2016
date says: 1472202758
du says: 0 1472206358 timestampTest
the times are different (an independent check of the time shows that
date is correct, so du must be wrong).
Note that on the other hand, human-readable time DOES work correctly for du.
input : date -r timestampTest +%c
output: Fri 26 Aug 2016 10:12:38 BST
input : du --time --time-style=+%c timestampTest
output: 0 Fri 26 Aug 2016 10:12:38 BST timestampTest
These are the same, as expected.
