NAME

BSON::Time - BSON type wrapper for date and time

VERSION

version v1.12.2

SYNOPSIS

    use BSON::Types ':all';

    bson_time();        # now
    bson_time( $secs ); # floating point seconds since epoch

DESCRIPTION

This module provides a BSON type wrapper for a 64-bit date-time value in the form of milliseconds since the Unix epoch (UTC only).

On a Perl without 64-bit integer support, the value must be a Math::BigInt object.

ATTRIBUTES

value

A integer representing milliseconds since the Unix epoch. The default is 0.

METHODS

epoch

Returns the number of seconds since the epoch (i.e. a floating-point value).

as_iso8601

Returns the value as an ISO-8601 formatted string of the form YYYY-MM-DDThh:mm:ss.sssZ. The fractional seconds will be omitted if they are zero.

as_datetime

Loads DateTime and returns the value as a DateTime object.

as_datetime_tiny

Loads DateTime::Tiny and returns the value as a DateTime::Tiny object.

as_mango_time

Loads Mango::BSON::Time and returns the value as a Mango::BSON::Time object.

as_time_moment

Loads Time::Moment and returns the value as a Time::Moment object.

TO_JSON

Returns a string formatted by "as_iso8601".

If the BSON_EXTJSON option is true, it will instead be compatible with MongoDB's extended JSON format, which represents it as a document as follows:

If the BSON_EXTJSON environment variable is true and the BSON_EXTJSON_RELAXED environment variable is false, returns a hashref compatible with MongoDB's extended JSON format, which represents it as a document as follows:

    {"$date" : { "$numberLong": "22337203685477580" } }

If the BSON_EXTJSON and BSON_EXTJSON_RELAXED environment variables are both true, then it will return a hashref with an ISO-8601 string for dates after the Unix epoch and before the year 10,000 and a $numberLong style value otherwise.

    {"$date" : "2012-12-24T12:15:30.500Z"}
    {"$date" : { "$numberLong": "-10000000" } }

OVERLOADING

Both numification (0+) and stringification ("") are overloaded to return the result of "epoch". Numeric comparison and string comparison are overloaded based on those and fallback overloading is enabled.
