it's not really silent - there's a sound change, but it's not gone; this isn't "knight" which sounds exactly like "night". You don't fully annunciate the t, but "imporant" would sound quite a bit different. The t has become a /ʔ/ - this is a common thing that happens to t. The apostrophe you indicate is a sign that you're still getting the glottal stop.
