Date difference

[Sboshoff76]

I read about the challenge of pulling digest and version data for current vs updated images.. so not expecting that; but would just the date or age data be easier to display?

I'll address this properly later, but a quick response for now to show I've seen your post.

Currently there's the -d option

-d N
Only update to new images that are N+ days old. Lists too recent with +prefix and age. 2xSlower.

Though that's just an either/or, either the update is older that N days or not. But with some rewrites that could instead/also list how old or when the image was released (with an additional flag, like -D).

The current code is:

datecheck() {
  ImageDate=$("$regbin" -v error image inspect "$RepoUrl" --format='{{.Created}}' | cut -d" " -f1)
  ImageEpoch=$(date -d "$ImageDate" +%s 2>/dev/null) || ImageEpoch=$(date -f "%Y-%m-%d" -j "$ImageDate" +%s)
  ImageAge=$(( ( $(date +%s) - ImageEpoch )/86400 ))
  if [[ "$ImageAge" -gt "$DaysOld" ]]; then
    return 0
  else
    return 1
  fi
}

I'll revisit this in the future! Currently occupied with other issues.
