DESCRIPTION
Makes manipulating time structures more convenient. Internally uses Time::Moment, Time::Piece and Time::Zone::Olson.
CONSTRUCTORS
new
my $t = Time::C->new();
my $t = Time::C->new($year);
my $t = Time::C->new($year, $month);
my $t = Time::C->new($year, $month, $day);
my $t = Time::C->new($year, $month, $day, $hour);
my $t = Time::C->new($year, $month, $day, $hour, $minute);
my $t = Time::C->new($year, $month, $day, $hour, $minute, $second);
my $t = Time::C->new($year, $month, $day, $hour, $minute, $second, $tz);
Creates a Time::C object for the specified time, or the current time if no $year is specified.
$year-
This is the year. If not specified,
new()will callnow_utc(). $month-
This is the month. If not specified it defaults to
1. $day-
This is the day of the month. If not specified it defaults to
1. $hour-
This is the hour. If not specified it defaults to
0. $minute-
This is the minute. If not specified it defaults to
0. $second-
This is the second. If not specified it defaults to
0. $tz-
This is the timezone specification such as
Europe/StockholmorUTC. If not specified it defaults toUTC.
localtime
my $t = Time::C->localtime($epoch);
my $t = Time::C->localtime($epoch, $tz);
Creates a Time::C object for the specified $epoch and optional $tz.
$epoch-
This is the time in seconds since the system epoch, usually
1970-01-01T00:00:00Z. $tz-
This is the timezone specification, such as
Europe/StockholmorUTC. If not specified defaults to the timezone specified in$ENV{TZ}, orUTCif that is unspecified.
gmtime
my $t = Time::C->gmtime($epoch);
Creates a Time::C object for the specified $epoch. The timezone will be UTC.
now
my $t = Time::C->now();
Creates a Time::C object for the current epoch in the timezone specified in $ENV{TZ} or UTC if that is unspecified.
now_utc
my $t = Time::C->now_utc();
Creates a Time::C object for the current epoch in UTC.
from_epoch
my $t = Time::C->from_epoch($epoch);
Creates a Time::C object for the specified $epoch. The timezone will be UTC.
from_string
my $t = Time::C->from_string($str);
my $t = Time::C->from_string($str, $format);
my $t = Time::C->from_string($str, $format, $expected_tz);
Creates a Time::C object for the specified $str, using the optional $format to parse it, and the optional $expected_tz to set an unambigous timezone, if it matches the offset the parsing operation gave.
$str-
This is the string that will be parsed by either "strptime" in Time::Piece or "from_string" in Time::Moment.
$format-
This is the format that "strptime" in Time::Piece will be given, by default it is
undef. If it is not defined, "from_string" in Time::Moment will be used instead. $expected_tz-
If the parsed time contains a zone or offset that parses, and the offset matches the
$expected_tzoffset,$expected_tzwill be set as the timezone. If it doesn't match, a generic timezone matching the offset will be set, such asUTCfor an offset of0. This variable will also default toUTC.
ACCESSORS
These accessors will work as LVALUEs, meaning you can assign to them to change the time being represented.
epoch
my $epoch = $t->epoch;
$t->epoch = $epoch;
$t->epoch += 3600;
$t->epoch++;
$t->epoch--;
Returns or sets the epoch according to the specified timezone.
tz
my $tz = $t->tz;
$t->tz = $tz;
$t = $t->tz($new_tz);
Returns or sets the timezone. If the timezone can't be recognised it dies.
If the form $t->tz($new_tz) is used, it instead changes the internal tz and returns the entire object.
offset
my $offset = $t->offset;
$t->offset = $offset;
$t->offset += 60;
Returns or sets the current offset in minutes. If the offset is set, it tries to find a generic Etc/GMT+X or +XX:XX timezone that matches the offset and updates the tz to this. If it fails, it dies with an error.
tm
my $tm = $t->tm;
$t->tm = $tm;
Returns a Time::Moment object for the current epoch and offset. On setting, it changes the current epoch.
string
my $str = $t->string;
my $str = $t->string($format);
$t->string = $str;
$t->string($format) = $str;
Renders the current time to a string using the optional strftime $format. If the $format is not given it defaults to undef. When setting this value, it tries to parse the string using "strptime" in Time::Piece with the $format or "from_string" in Time::Moment if no $format was given or strptime fails. If the detected offset matches the current tz, that is kept, otherwise it will get changed to a generic tz in the form of Etc/GMT+X or +XX:XX.
year
my $year = $t->year;
$t->year = $year;
$t->year += 10;
$t->year++;
$t->year--;
Returns or sets the current year, updating the epoch accordingly.
quarter
my $quarter = $t->quarter;
$t->quarter = $quarter;
$t->quarter += 4;
$t->quarter++;
$t->quarter--;
Returns or sets the current quarter of the year, updating the epoch accordingly.
month
my $month = $t->month;
$t->month = $month;
$t->month += 12;
$t->month++;
$t->month--;
Returns or sets the current month of the year, updating the epoch accordingly.

$t->week = $week;
$t->week += 4;
$t->week++;
$t->week--;
Returns or sets the current week or the year, updating the epoch accordingly.
day
my $day = $t->day;
$t->day = $day;
$t->day += 31;
$t->day++;
$t->day--;
Returns or sets the current day of the month, updating the epoch accordingly.
day_of_month

$t->day_of_week += 7;
$t->day_of_week++;
$t->day_of_week--;
Returns or sets the current day of the week, updating the epoch accordingly. This module uses Time::Moment which counts days in the week starting from 1 with Monday, and ending on 7 with Sunday.

my $hour = $t->hour;
$t->hour = $hour;
$t->hour += 24;
$t->hour++;
$t->hour--;

second
my $second = $t->second;
$t->second = $second;

$t->millisecond = $msec;
$t->millisecond += 1000;
