net::dns::sec::tools::timetrans
timetrans(3pm) User Contributed Perl Documentation timetrans(3pm)
NAME
Net::DNS::SEC::Tools::timetrans - Convert an integer seconds count into text units.
SYNOPSIS
use Net::DNS::SEC::Tools::timetrans;
$timestring = timetrans(86488);
$timestring = fuzzytimetrans(86488);
DESCRIPTION
The timetrans() interface in Net::DNS::SEC::Tools::timetrans converts an integer seconds count into the equivalent number of days, hours,
and minutes. The time converted is a relative time, not an absolute time. The returned time is given in terms of days, hours, minutes,
and seconds, as required to express the seconds count appropriately.
The fuzzytimetrans() interface converts an integer seconds count into the equivalent number of weeks or days or hours or minutes. The unit
chosen is that which is most natural for the seconds count. One decimal place of precision is included in the result.
INTERFACES
The interfaces to the Net::DNS::SEC::Tools::timetrans module are given below.
timetrans()
This routine converts an integer seconds count into the equivalent number of days, hours, and minutes. This converted seconds count is
returned as a text string. The seconds count must be greater than zero or an error will be returned.
Return Values:
If a valid seconds count was given, the count converted into the
appropriate text string will be returned.
An empty string is returned if no seconds count was given or if
the seconds count is less than one.
