.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Objects of this class store and manipulate metadata for time columns in a database.  Column metadata objects store information about columns (data type, size, etc.) and are responsible for creating object methods that manipulate column values.
.PP
This class inherits from Rose::DB::Object::Metadata::Column. Inherited methods that are not overridden will not be documented a second time here.  See the Rose::DB::Object::Metadata::Column documentation for more information.

.SH "OBJECT METHODS"
.IX Header "OBJECT METHODS"
.IP "\fBparse_value \s-1DB\s0, \s-1VALUE\s0\fR" 4
.IX Item "parse_value DB, VALUE"
Convert \s-1VALUE\s0 to the equivalent Time::Clock object.  \s-1VALUE\s0 maybe returned unmodified if it is a valid time keyword or otherwise has special meaning to the underlying database.  \s-1DB\s0 is a Rose::DB object that is used as part of the parsing process.  Both arguments are required.
.IP "\fBprecision [\s-1INT\s0]\fR" 4
.IX Item "precision [INT]"
Get or set the precision of the time value.  The precision is the total count of digits in the whole time.  For example, 12:34 has a precision of 4, and 12:34:56.12 has a precision of 8.  The precision value must be 2, 4, or greater than or equal to 6.  The default precision is 6.  When the precision is set, the scale is also set automatically.
.IP "\fBscale [\s-1INT\s0]\fR" 4
.IX Item "scale [INT]"
Get or set the integer number of places past the decimal point preserved for fractional seconds.  The default scale is 0.  When the scale is set, the precision is also set automatically.
.Sp
Returns \*(L"time\*(R".
.IP "\fBtype\fR" 4
.IX Item "type"
Returns \*(L"time\*(R".
