After a two months long wait, i just got my ID card in hand.

and there is another enquery come up to me, wish if anyone could help?
My initial work permit visa was granted on 17/04/2008, and this time I switched to tier2 under transitional arrangements. Refer to the HO site, it shows me:
If your previous permission to stay was as a work permit holder, you can apply under the transitional arrangements for permission to stay for the period of time you need to take your total stay in the United Kingdom to five years in an eligible category or for two years if this is longer (beginning on the start date given on your certificate of sponsorship).

Thus, my new leave to remain date should be end up to 17/4/2013? Am I right?
Many thanks.
