Package: mencal
Version: 2.3-7
Severity: normal
Tags: patch
mencal does not account for daylight savings time when calculating the
variable '$day' in the markdays() subroutine, resulting in fractional
values for '$day', which breaks mencal if the start date and current
date are in different daylight savings time states.
This may actually be due to changed behaviour in POSIX::mktime back in
2007, where mktime now sets isdst=-1 by default, instead of setting
isdst=0 by default.
The included patch fixes this problem simply by ensuring that '$day' is
an integer.
