# I want to sync the local clock but don't have access to any NTP server.
# Website https://time.is tells me the time difference of my system clock and I can manually adjust the local clock.

# But then I recall that a HTTP response often contains a date header with current time in GMT timezone.
# I'll use it to set the system clock with the precision of 1 or 2 seconds.
# When I need more accurate time, I can use `datetime` (or `utc_datetime`) from `http://worldtimeapi.org/api/ip.txt`

# time from worldtimeapi.org has millisecond precision, you can use it to compare with your system time:
date -uIns && time curl -s http://worldtimeapi.org/api/ip.txt | sed -n 's/^utc_datetime://p'
date -Ins && time curl -s http://worldtimeapi.org/api/ip.txt | sed -n 's/^datetime://p'

// while reading "Why List Comprehension is Bad" (http://xahlee.info/comp/list_comprehension.html),
// I notice that JS don't have integer list generator like 0..9 or range(0,9)

// I wanna see if a one-liner can generate 1 list of integer i where 0 <= i < 9
