Put this into AwkCommandFile:

Code:
BEGIN { FS="," }
{ _[NR] = $0 }
END {
  m = "%.2f"
  for (i=1; i<=NR; i++) {
    if (_[i]) {
    print _[i] > "out1"
    split(_[i], tt)
    delete _[i]
    for (j=1; j<=NR; j++) {
      if (_[j]) {
      split(_[j], t)
      if ((sprintf(m, t[2] - v) <= sprintf(m, tt[2]) && \
sprintf(m, tt[2]) <= sprintf(m, t[2] + v)) && \
      (sprintf(m, t[3] - v) <= sprintf(m, tt[3]) && \
sprintf(m, tt[3]) <= sprintf(m, t[3] + v))) {
        print _[j] > "out2"
        delete _[j]
      }
     }
    }
   }
  }
 }

Run it like this:

Code:
awk -f AwkCommandFile v=1.1 InputFile

I put the v variable outside the script for commodity (you can run the script with different values without modifying the code).

vfs_readonly

VFS_READONLY(8) 														   VFS_READONLY(8)

NAME

       vfs_readonly - make a Samba share read only for a specified time period

SYNOPSIS

       vfs objects = readonly

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       The  vfs_readonly  VFS  module  marks a share as read only for all clients connecting within the configured time period. Clients connecting
       during this time will be denied write access to all files in the share, irrespective of ther actual access privileges.

       This module is stackable.

OPTIONS

       readonly:period = BEGIN, END
	  Only mark the share as read only if the client connection was made between the times marked by the BEGIN and END  date  specifiers.  The
	  syntax of these date specifiers is the same as that accepted by the -d option of GNU date(1).

EXAMPLES

       Mark all shares read only:

	       [global]
	    vfs objects = readonly

       Mark the [backup] share as read only during business hours:

	       [backup]
	    path = /readonly
	    vfs objects = readonly
	    readonly:period = readonly:period = "today 9:00","today 17:00"

VERSION

       This man page is correct for version 3.0.25 of the Samba suite.

AUTHOR

       The  original  Samba  software  and  related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
