local chilkat = require("chilkat")

local dt = chilkat.DateTime.new()

-- Set to the current system date/time.
dt:set_from_current_system_time()
print("Now: " .. dt:get_as_timestamp(true))

-- Subtract 10 minutes, making the date 10 minutes in the past.
dt:add_seconds(-600)
print("10 minutes ago: " .. dt:get_as_timestamp(true))

-- Is the date/time older than 10 seconds?
local b = dt:older_than(10, "seconds")
print("Older than 10 seconds: " .. tostring(b))

-- Is the date/time older than 5 minutes?
b = dt:older_than(5, "minutes")
print("Older than 5 minutes: " .. tostring(b))

-- Is the date/time older than 15 minutes?
b = dt:older_than(15, "minutes")
print("Older than 15 minutes: " .. tostring(b))

-- Is the date/time older than 1 hour?
b = dt:older_than(1, "hour")
print("Older than 1 hour: " .. tostring(b))

-- Is the date/time older than 1 day?
b = dt:older_than(1, "day")
print("Older than 1 day: " .. tostring(b))

-- Output:

--     Now: 2017-05-05T23:33:06-0500
