All the subtraction done on fields ($2,$10) depends on year on field $4, the variance defined.
If no input on $2 matches string PP<number>, $2 is printed as is, unchanged.
If no input on $10 matches string RHS, $10 is printed as is, unchanged.

Dear Expert,
Is there a command to do that in Unix?
In such a way that we don't need to actually "write" or

Hi all,
I'm using Red Hat Linux and want to move some folders and files around but not change the modified date. Is this possible?
I know cp has a -p flag which seems to do what I want, but this is a large volume of data so copying and deleting would not be feasible. (13 Replies)

sttime
sttime(3) ShapeTools Toolkit Library sttime(3)NAME
stMktime, stWriteTime - date and time handling
SYNOPSIS
#include <config.h>
#include <sttk.h.h>
time_tstMktime (char *string);
char*stWriteTime (time_t date);
DESCRIPTION
stMktime scans the given string and tries to read a date and time from it. It understands various formats of date strings. The following is
a list of all valid formats, optional parts in brackets.
[Tue] Jan 5[,] [19]93
This includes the standard asctime(3) format.
Jan 5 With no year given, the year defaults to the current year.
[19]93/01/05 This notation requires month and day represented by exactly two digits.
5.1.[19]93 This is the usual German notation.
5.1. German notation referencing the current year.
A certain time, given together with the date must always have the following form.
hours:minutes[:seconds]
Each of the fields must be an integer value within the proper range (hours: 0-23, minutes and seconds: 0-59). Values below
10 may be written as one digit numbers.
The time value may be placed anywhere in the date string: at the beginning, at the end, or somewhere in the middle. Any amount of white-
space may be given between a field of the time value and the separating colon. The time is always considered to be local time.
stWriteTime generates a time string similar to asctime(3) from its date argument.
SEE ALSO asctime(3)BUGS
Time Zone Names within the time string (like `MET') are not handled properly. In most cases they will cause a failure.
