If `org-timer-default-timer' is not zero, suggest this value as

prompt the user if she wants to replace it.

Called with a numeric prefix argument, use this numeric value as
the duration of the timer.

Called with a `C-u' prefix arguments, use `org-timer-default-timer'

With two `C-u' prefix arguments, use `org-timer-default-timer'

By default, the timer duration will be set to the number of
minutes in the Effort property, if any.  You can ignore this by
