Defect #18984: migrate_from_mantis with NoMethodError: strftime - Redmine

Defect #18984

Updated by Toshi MARUYAMA almost 10 years ago

 
 I am migrating from Mantis 1.1.8 to Redmine 2.6.1.stable 

 Using: rake --trace redmine:migrate_from_mantis RAILS_ENV="production" 

 I get the following error: 
    NoMethodError: undefined method `strftime' for 1411982898:Fixnum 

 I have applied: #10504 
 http://www.redmine.org/issues/10504 

 But with no success. 

 Any hints?
