I cannot comment on the tablets as I only take insulin.
The purpose of your daily night time insulin is to work with the glucose that drips from your liver throughout the day and night. This once a day insulin is often called basal is a long acting insulin that lasts about 24 hours. Therefore, it should continue to be taken about 24 hours apart regardless of what time you go to bed. Most long acting insulin is ok if you take it one hour earlier or later.
Just to add, some basal insulins are taken twice a day. These last about 12 hours.
