Thanks for pointing out. The local version had only .toLocaleString().
Compatibility per my current research is as follows:

JavaScript JScript ES JSC² KJS³ Opera
___________________________________________________________________________
..toDateString() 1.8 (N/A) 5.5.6330 (5.5) 3 530.17 3.5.9 5.02
..toGMTString() [S] 1.3 (1.0¹) 5.1.5010 (1.0) 1 530.17 3.5.9 5.02
..toLocaleDateString() 1.8 (1.0*) 5.5.6330 (5.5) 3 530.17 3.5.9 5.02
..toLocaleFormat(...) 1.8 (1.6) - - - - - -
..toLocaleString() [S] 1.3 (1.0) 5.1.5010 (1.0) 1 525.13 3.5.9 5.02
..toLocaleTimeString() 1.8 (1.0*) 5.5.6330 (5.5) 3 530.17 3.5.9 5.02
..toString() [S] 1.3 (1.1) 5.1.5010 (2.0) 1 530.17 3.5.9 5.02
..toSource() 1.3 (1.3) - - - - - -
..toTimeString() 1.8 (N/A) 5.5.6330 (5.5) 3 530.17 3.5.9 5.02
..toUTCString() [S] 1.3 (1.3) 5.1.5010 (3.0) 1 530.17 3.5.9 5.02

The versions here I have tested to date; text in parantheses denotes what is
documented instead, `*' denotes documentation that contradicts tests.

The completed Matrix (at <http://PointedEars.de/es-matrix>) will probably
feature sourced, documented, assumed, and tested versions. The versions
here denote the minimum requirements; newer versions are expected to support
the respective feature, too; tests have not shown otherwise.

Features marked with `[S]' can be considered safe according to these results
and based on the assumption that earlier versions are obsolete because the
user agents known to implement them can be considered obsolete. Note that
this assessment is likely to be subject to change as more implementations
are evaluated. If taken as a recommendation for design decisions, it should
be taken as a light one.
