                 anoms = c(1, 1, 1, 1, 1, 2), syndrome = c("Acrosyndrome", 
                                                       "Acrosyndrome", "Acrosyndrome", "Acrosyndrome", "Acrosyndrome", 
                                                       "Acrosyndrome")), .Names = c("timestamp", "anoms", "syndrome"
                                                       ), row.names = c(NA, 6L), class = "data.frame")

With the development version of DT (>= 0.2.2) on Github, you can pass additional parameters to the date conversion method, e.g.

datatable(a) %>%
  formatDate(1, method = 'toLocaleDateString', params = list('fr-FR'))

Or more parameters:

datatable(a) %>% formatDate(
  1, method = 'toLocaleDateString',
  params = list('fr-FR',  list(year = 'numeric', month = 'long', day = 'numeric'))
)
