I'm trying to do some simple math on a 24 hour time base.
The time is in the format of HM (HoursMinutes)
For example:
2330 #23:30
1800 #18:00
730 #07:30
my problem is with the single-digit hours. If the time is 2200, I use this code:
baseTime=2200

Hi,
The timestamp is June 06 2011 11:05AM
i need 2 results.
first, an hour added to it, June 06 2011 12:05AM
second, a minute added to it, June 06 2011 11:06AM
How can i do this?
Also when it reaches 12:59, it needs to start from 1 again without giving the output as 13:00. it... (17 Replies)
Hi all,
I need your help to increment a time by one hour.
The difficulty is the time is in a string format and not a value
cat file | awk '{print $1,$2}'

09/03/2011 20:11
I want to change the time to be as follows
09/02/2011 21:11 or even 09/02/2011 20:21

This is a new one on me. We upgraded a system from AIX 5.3 TL 7 to 6.1 TL 7 yesterday. The app people notified us that their cron jobs weren't running at the right time. So I made a test cron entry and here's what I've found:

Hello All,
Is there any *easy* and efficient way to add "one hour" to few fields in a file? . I have done this using a python script and it has hit with performance issues.
I have around 200mi of records, which I need to modify and send across in one hour.

Time on unix server shows 8:00a CST
Time on Windows 7 Box shows 8:00a CST
However when you access an NFS share the time stamp on the files show an hour ahead? Talking about a newly created file shows an hour ahead so at 8:00a the file will show a time stamp of 9:00a CST

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
