I have a value such as 'timestamp' below, where the last three digits correspond to milliseconds.

timestamp = 1340830988768

I currently have code that looks like the following:

import indicate
indicator = indicate.Indicator()
indicator.set_property_time("time", int(timestamp[:-3]))

I want to amend it to use:

from gi.repository import Indicate
indicator = Indicate.Indicator()

However, the new version of set_property_time requires the second parameter to be a GLib.TimeVal. How do I create a GLib.TimeVal from my timestamp? Millisecond precision is not important for this application.
