With ksh93 (often installed by default on commercial SysV based unices like AIX or Solaris), which also happens to be the /bin/sh of Solaris 11 and newer:
date=2019-02-08T19:24:30.220Z
export LC_ALL=C # to make sure the decimal radix is "."
then_in_seconds=$(printf '%(%s.%N)Tn' "$date")
now_in_seconds=$(printf '%(%s.%N)Tn' now)
difference_in_seconds=$((now_in_seconds - then_in_seconds))
difference_in_24h_periods=$((difference_in_seconds / 24 / 60 / 60))
echo "Result: $difference_in_24h_periods"
At 2019-02-20T11:17:30Z and a bit, that gave me:
Result: 11.6618110817684377
You can use $((f(difference_in_24h_periods))) where f is one of round, floor, ceil, nearbyint, trunc, rint, int like in C if you want the difference as an integer, or use printf format specifications to specify the number of significant digits.
With zsh:
zmodload zsh/datetime
date=2019-02-08T19:24:30.220Z
TZ=UTC0 strftime -rs then_in_seconds '%Y-%m-%dT%H:%M:%S' "$date%.*"
then_in_seconds+=.$$date##*.%Z
now_in_seconds=$EPOCHREALTIME
difference_in_seconds=$((now_in_seconds - then_in_seconds))
difference_in_24h_periods=$((difference_in_seconds / 24 / 60 / 60))
echo "Result: $difference_in_24h_periods"
