Please be aware that your data are not a linear function of time; on top of some noise it has a small curvature, and the six data points right after the gap are somewhat lower than they should be (there's a jump in values but not in time delta at point 7).
This is a quick and dirty approximation to exactly your problem and data; no error checking etc. is done. It's sort of a linear interpolation between the given boundaries although we know the boundary to the right is questionable. On top, my mawk has a problem with the D1 > D0 comparison, sometimes the delta is -1E-16, sometimes it's +71E-16, so a few extra lines are being "interpolated". I don't have a good solution at hand; either increase the to be compared value slightly (yuck!) or use sort -u on the result (yuck!)...

I am very new to shell scripting. We use C-Shell here and I know the issues that surround it. I hope a solution can be created using awk, sed, etc... instead of having to write a program.

Hi Experts ,
I need your help to collect the complete data between two time frame from the log files, when I try awk it's collecting the data only which is printed with time stamp
for example, awk works well from "16:00 to 17:30" but its not collecting <line*> "from 17:30 to 18:00"

PLSCMAP1L(3plplot) PLplot API PLSCMAP1L(3plplot)NAME
plscmap1l - Set color map1 colors using a piece-wise linear relationship
SYNOPSIS
plscmap1l(itype, npts, pos, coord1, coord2, coord3, rev)
DESCRIPTION
Set color map1 colors using a piece-wise linear relationship between position in the color map (from 0 to 1) and position in HLS or RGB
color space (see the PLplot documentation). May be called at any time.
The idea here is to specify a number of control points that define the mapping between palette 1 input positions (intensities) and HLS (or
RGB). Between these points, linear interpolation is used which gives a smooth variation of color with input position. Any number of con-
trol points may be specified, located at arbitrary positions, although typically 2 - 4 are enough. Another way of stating this is that we
are traversing a given number of lines through HLS (or RGB) space as we move through color map1 entries. The control points at the minimum
and maximum position (0 and 1) must always be specified. By adding more control points you can get more variation. One good technique for
plotting functions that vary about some expected average is to use an additional 2 control points in the center (position ~= 0.5) that are
the same lightness as the background (typically white for paper output, black for crt), and same hue as the boundary control points. This
allows the highs and lows to be very easily distinguished.
Each control point must specify the position in color map1 as well as three coordinates in HLS or RGB space. The first point must corre-
spond to position = 0, and the last to position = 1.
The hue is interpolated around the "front" of the color wheel (red<->green<->blue<->red) unless the "rev" flag is set to true, in which
case interpolation (between the i and i + 1 control point for rev[i]) proceeds around the back (reverse) side. Specifying rev=NULL is
equivalent to setting rev[]= false for every control point.
