require 'chilkat'

# Specify the NTP server domain.
# Information is passed in a JSON object to allow for any unanticipated future optional information that might need to be provided.
json = Chilkat::CkJsonObject.new()
json.UpdateString("ntp_server","pool.ntp.org")

# Query the NTP server for the current date/time.
dt = Chilkat::CkDateTime.new()
# Note: The SetFromNtpServer method is available starting in v9.5.0.96 for most Chilkat builds, but not all.
# If the SetFromNtpServer method is not present, contact support@chilkatsoft.com for a hotfix build.
# It should be available in all programming languages/platforms starting in v9.5.0.97
success = dt.SetFromNtpServer(json.emit())
if (success == false)
    print dt.lastErrorText() + "\n";
    exit
end

# Show the date/time in various formats..
bLocalTime = true
print dt.getAsTimestamp(bLocalTime) + "\n";
print dt.getAsRfc822(bLocalTime) + "\n";
print dt.GetAsUnixTime(bLocalTime).to_s() + "\n";
