Comment(by bshanks):

 workaround (for the convenience of people who need to argmin dates):

 from numpy import isnan
 def argmin(listable):
     xs = list(listable)
     current_min = xs[0]
     current_min_loc = 0
     for i in range(len(xs)):
         item = xs[i]
         if item < current_min:
             current_min = item
             current_min_loc = i
             if isnan(item):
                 current_min = item
                 current_min_loc = i
         except TypeError:
     return current_min_loc
