bugs - set timefmt and xrange

[Petr M. <mi...@ph...>]

I think I have found two places where time settings accept string but not 
string variable or string functions:

1. Here "set timefmt" does not accept string variable:

set xdata time
set timefmt "[%Y/%m/%d %H:%M:%S]"
show timefmt

myfmt = "%Y/%m/%d %H:%M:%S"
set timefmt myfmt

gnuplot> set timefmt myfmt
                     ^
         "bug1.gp", line 8: time format string expected


2. "set xrange" accepts string variables but not string functions:

reset

set xdata time
set timefmt "%Y/%m/%d %H:%M:%S"

set xrange [ "2012/01/20 14:00:00" : "2012/01/20 18:00:00" ]
show xrange

s1="2012/01/20 14:00:00"; s2="2012/01/20 18:00:00"
set xrange [ s1 : s2 ] 
show xrange

set xrange [sprintf("2012/01/20 14:00:00") : sprintf("2012/01/20 18:00:00")]
show xrange

myfmt = "%Y/%m/%d %H:%M:%S"
x1=strptime(myfmt, "2012/01/20 14:00:00")
x2=strptime(myfmt, "2012/01/20 18:00:00")

set xrange [ strftime(myfmt, x1) : strftime(myfmt, x2) ]
show xrange

=>

        set xdata time
        set xrange [ "2012/01/20 14:00:00" : "2012/01/20 18:00:00" ] 

        set xdata time
        set xrange [ "2012/01/20 14:00:00" : "2012/01/20 18:00:00" ] 

        set xdata time
        set xrange [ "2000/01/01 00:33:32" : "2000/01/01 00:33:32" ] 

        set xdata time
        set xrange [ "2000/01/01 00:33:32" : "2000/01/01 00:33:32" ] 

... the first two outputs are correct.
