CodeFluent Entities provides an option to remove the "generation date and time" when running producers. The option may be defined at the producer level or at the project level (applied to all of your producers)
- At producer level
Select the producer and set the productionFlags property to "RemoveDates"
<cf:producer productionFlags="Overwrite, RemoveDates">
</cf:producer>
- At project level
Select the project and set the defaultProducerProductionFlag property (in the advanced tab) to "RemoveDates"
<cf:project defaultProducerProductionFlags="Overwrite, RemoveDates">
The procedure is explained on The Codefluent Entities blog: http://blog.codefluententities.com/2013/04/22/remove-the-current-date-and-time-to-generated-files/
