 =head1 DESCRIPTION
 
-These routines are the inverse of built-in perl functions localtime()
-and gmtime().  They accept a date as a six-element array, and return
-the corresponding time(2) value in seconds since the system epoch
-(Midnight, January 1, 1970 GMT on Unix, for example).  This value can
-be positive or negative, though POSIX only requires support for
-positive values, so dates before the system's epoch may not work on
-all operating systems.
+This module provides functions that are the inverse of built-in perl
+functions C<localtime()> and C<gmtime()>. They accept a date as a
+six-element array, and return the corresponding C<time(2)> value in
+seconds since the system epoch (Midnight, January 1, 1970 GMT on Unix,
+for example). This value can be positive or negative, though POSIX
+only requires support for positive values, so dates before the
+system's epoch may not work on all operating systems.
 
 It is worth drawing particular attention to the expected ranges for
-the values provided.  The value for the day of the month is the actual day
-(ie 1..31), while the month is the number of months since January (0..11).
-This is consistent with the values returned from localtime() and gmtime().
-
-The timelocal() and timegm() functions perform range checking on the
-input $sec, $min, $hour, $mday, and $mon values by default.  If you'd
-rather they didn't, you can explicitly import the timelocal_nocheck()
-and timegm_nocheck() functions.
-
-       use Time::Local 'timelocal_nocheck';
-
-       {
-           # The 365th day of 1999
-           print scalar localtime timelocal_nocheck 0,0,0,365,0,99;
-
-           # The twenty thousandth day since 1970
-           print scalar localtime timelocal_nocheck 0,0,0,20000,0,70;
-
-           # And even the 10,000,000th second since 1999!
-           print scalar localtime timelocal_nocheck 10000000,0,0,1,0,99;
-       }
-
-Your mileage may vary when trying these with minutes and hours,
-and it doesn't work at all for months.
-
-Strictly speaking, the year should also be specified in a form consistent
-with localtime(), i.e. the offset from 1900.
-In order to make the interpretation of the year easier for humans,
-however, who are more accustomed to seeing years as two-digit or four-digit
-values, the following conventions are followed:
+the values provided. The value for the day of the month is the actual
+day (ie 1..31), while the month is the number of months since January
+(0..11). This is consistent with the values returned from
+C<localtime()> and C<gmtime()>.
+
+=head1 FUNCTIONS
+
+This module exports two functions by default, C<timelocal()> and
+C<timegm()>.
+
+The C<timelocal()> and C<timegm()> functions perform range checking on
+the input $sec, $min, $hour, $mday, and $mon values by default.
+
+If you are working with data you know to be valid, you can speed your
+code up by using the "nocheck" variants, C<timelocal_nocheck()> and
+C<timegm_nocheck()>. These variants must be explicitly imported.
+
+    use Time::Local 'timelocal_nocheck';
+
+    # The 365th day of 1999
+    print scalar localtime timelocal_nocheck 0,0,0,365,0,99;
+
+If you supply data which is not valid (month 27, second 1,000) the
+results will be unpredictable (so don't do that).
+
+=head2 Year Value Interpretation
+
+Strictly speaking, the year should be specified in a form consistent
+with C<localtime()>, i.e. the offset from 1900. In order to make the
+interpretation of the year easier for humans, however, who are more
+accustomed to seeing years as two-digit or four-digit values, the
+following conventions are followed:
 
 =over 4
 
 =item *
 
 Years greater than 999 are interpreted as being the actual year,
-rather than the offset from 1900.  Thus, 1964 would indicate the year
+rather than the offset from 1900. Thus, 1964 would indicate the year
 Martin Luther King won the Nobel prize, not the year 3864.
 
 =item *
 
-Years in the range 100..999 are interpreted as offset from 1900, 
-so that 112 indicates 2012.  This rule also applies to years less than zero
-(but see note below regarding date range).
+Years in the range 100..999 are interpreted as offset from 1900, so
+that 112 indicates 2012. This rule also applies to years less than
+zero (but see note below regarding date range).
 
 =item *
 
 Years in the range 0..99 are interpreted as shorthand for years in the
-rolling "current century," defined as 50 years on either side of the current
-year.  Thus, today, in 1999, 0 would refer to 2000, and 45 to 2045,
-but 55 would refer to 1955.  Twenty years from now, 55 would instead refer
-to 2055.  This is messy, but matches the way people currently think about
-two digit dates.  Whenever possible, use an absolute four digit year instead.

 =head1 IMPLEMENTATION
 
-These routines are quite efficient and yet are always guaranteed to agree
-with localtime() and gmtime().  We manage this by caching the start times
-of any months we've seen before.  If we know the start time of the month,
-we can always calculate any time within the month.  The start times
-are calculated using a mathematical formula. Unlike other algorithms
-that do multiple calls to gmtime().
-
-timelocal() is implemented using the same cache.  We just assume that we're
-translating a GMT time, and then fudge it when we're done for the timezone
-and daylight savings arguments.  Note that the timezone is evaluated for
-each date because countries occasionally change their official timezones.
-Assuming that localtime() corrects for these changes, this routine will
-also be correct.
