Full Discussion: Urgent for date increment

If you want to reduce the number of date executions, try also (given your shell offers "process substitution", and date has the -f option):

Code:
$ DAYS=20
$ STARTDT=$(date +%s)
$ ENDDT=$((STARTDT + 86400 * DAYS))
 $ for ((STARTDT; STARTDT<ENDDT; STARTDT+=86400)); do echo @$STARTDT; done > >(date -f-)

EDIT: or even
Code:
for ((; (STARTDT+=86400)<ENDDT;  )); do echo @$STARTDT; done > >(date -f-)

px_date2string

PX_DATE2STRING(3)					     Library Functions Manual						 PX_DATE2STRING(3)

NAME

       PX_date2string -- Convert paradox date into formated string

SYNOPSIS

       #include <paradox.h>

       char * PX_date2string(pxdoc_t *pxdoc, long date, const char *format)

DESCRIPTION

       Creates	a  string  representation  of  a  paradox  date  as  specified	in  the  parameter format.  The date must be either retrieved with
       PX_get_data_long(3)  after  calling  PX_get_record(3)  or  by  simply  using  the  long	value  in  the	pxval_t  struct  as  returned	by
       PX_retrieve_record(3).  The function uses internally the PX_timestamp2string(3) function.  The format string may contain all chars as docu-
       mented with PX_timestamp2string(3), though only those concerning the date will produce resonable results.

RETURN VALUE

       Returns pointer to string on success and NULL on failure.

SEE ALSO

       PX_timestamp2string(3), PX_time2string(3)
