License renewal and a leap year

I have just renewed my subscription for 12 months. The old subscription expired on the 20th January 2020 (or was valid up and until midnight on the 20/1/2020). When I activated the renewal, it was only valid until the 19th January 2021, i.e 21/1/2020 to 19/1/2021. This is a day short, according to my calculations; it should be 21/1/2020 to 20/1/2021. I suspect that because 2020 is a leap year, adding 365 days, rather than 366, is the cause. I have logged a case with Sophos support and I will report back here with the outcome. Meantime, if you are renewing in 2020, before the 29th February, for 12 months you may want to check the expiry date.

  • I am going to reject Paul's answer which has been set as the verified answer as detailed below.

    - the FAQ example at Why didn't I get the full term when I activated my license key? illustrates the point I have been trying to make all along. The example in words (the diagram is a bit confusing) is that a renewed subscription activated 2 months after the old one expired, is modified (back dated) by subtracting 2 months so the expiry date is the same as if the renewal occurred when the old subscription expired. This is not 10 months from the old expiry date as seems to be the response from Sophos, but 10 months from when the new subscription was activated. This is what I would expect any organisation offering subscriptions to do, or everybody would take advantage.

    - in my case I activated the renewal on the 22/1/2020. Without back dating the expiry would have been 21/1/2021. Back dating, if my math is correct, should have subtracted a day, making the expiry the 20/1/2021. Instead it was set to the 19/1/2021, a subtraction of 2 days.

    So I still believe there is a bug somewhere where the calculation for working out the subtraction is a day out. And we are in a leap year!

    And the generosity of the licensing team, is actually a work around for a bug.

    I have had a browse through the legal stuff at https://www.sophos.com/en-us/legal and could find no reference to the back tracking for subscription renewal. I would expect it to be there somewhere, or Sophos might have a legal problem if it was challenged.

  • Hi Jon,

    Thanks for your reply and the effort you have put in to research and analyse this. The issue of rounding a fraction of a day up or down is one issue, but I also see your point that that only explains one 'lost' day and not the other one. I agree with your analysis and have updated our internal bug report with the points you have put forward.

    Regards,

    Paul
