Comment 1 for bug 1156520

In order to implement this we will need to do following:

Instead of creating date label when main label is missing we will need to show non-editable date label when main label is missing. We already have date column in DB (see insertDate) therefore DB side is not affected.

Changing over-time is more complicated to implement. To avoid slowness in calculator we might take two approaches:

1) Assume that user will close and open calculator frequently and update date information only on start;

2) Use timer and update date information each 5 minutes (I think that's delta user will tolerate).

As well I highly recommend reusing the fact that history is always go date-by-date - our list is always consistent. Therefore when first entry older than one week is met we can stop updating text of dates because exact date is used in such cases.
