The '-t' option of the replay command does not work.

the syntax is : -t field type from to

Where:
- field is the title of the column used as absciss (time)
- type is either 'long', meaning that the time is expressed as the number of milliseconds since 1/1/1970. This is the type of the field.
- from, to: are the lower and higher bound of the time interval. The syntax must be : "yyyy/MM/dd HH:mm:ss" (see SimpleDateFormat).

The commands tries to parse from and to according to the 'type' definition, instead of the human readable form "yyyy/MM/dd HH:mm:ss".
