DateDiff shows different results depending on the format

[Lamyergeier]

function DateDuration() {
 DateOther=${1:?"Enter a date in iso format. e.g. \$(date --iso-8601=seconds -d 'last mon')"}
 DateNow=$(date --iso-8601=seconds -d "now") # Current date in ISO Format

 datediff -f '%Y years, %m months, %d days, %H:%0M:%0S' "${DateNow}" "${DateOther}"
 datediff -f '%d days, %H:%0M:%0S' "${DateNow}" "${DateOther}"
 }
 ```

 ```bash
 $ DateDuration $(date --iso-8601=seconds -d 'last tue')
 -0 years, 0 months, 3 days, 6:23:34
 -2 days, 17:36:26
 ```

As can be seen the answers don't match!
