OSI SAF: Bug in time variables on sea ice edge and type products

The OSI SAF sea ice edge and type products (OSI-402-d and OSI-403-d) have a bug in the time and time_bnds variables. The time variable currently gives the start time of the daily product, while it should give the central time. So the time variable is presently 12 hours shifted. 
The time_bnds variable currently gives the start time twice, instead of giving the start and end time of the daily product.
This will be corrected on the products with time stamp 2021-11-01 12:00 UTC and onwards, that is the products distributed on 2021-11-02 04:30 UTC.

The FTP archive of products will also be updated on 2021-11-01, around 12:30 CET. Products with time stamp from 2021-06-01 12:00 UTC up to present will be corrected.

Test products with corrected time variables are available here for users to check the change: and
