## Date and time fields in lino.modlib.export_excel¶

(Continued from yesterday.)

The new test case Exporting to Excel did not yet cover the actual problem. Now it also tests the cell values of the generated file.

While testing this I saw that time values could be handled the same way and added them. I also moved the variables date_style: instead of instantiating them for every column, I defined them as class variables.

### Tested Lino Così¶

I had a tour on Lino Così in order to check whether recent changes had affected the printing of invoices there.

Fixed a bug which caused the combobox on ml.ledger.Journal.template to remain empty.

TODO: add the lino.modlib.notes module to Lino Così and add a possibility to write payment reminders.

### Continued on docs/tickets/136¶

Until now I had the following template code (in presence_certificate.body.html):

{% set times = (dd.strftime(obj.waiting_since),
dd.strftime(obj.gone_since)) %}


Changed this to:

{% set times = (dd.strftime(obj.waiting_since),
dd.strftime(obj.gone_since or this.time)) %}


And added a new property lino.modlib.excerpts.Excerpt.time.
