51 RT::Date - a simple Object Oriented date.
59 RT Date is a simple Date Object designed to be speedy and easy for RT to use
61 The fact that it assumes that a time of 0 means "never" is probably a bug.

147 If $args->{'Format'} is ISO, tries to parse an ISO date.
149 If $args->{'Format'} is 'unknown', require Time::ParseDate and make it figure
150 things out. This is a heavyweight operation that should never be called from
151 within RT's core. But it's really useful for something like the textbox date
152 entry where we let the user do whatever they want.

975 Takes one mandatory argument C<$context>, which determines whether

977 argument unix C<$time>, default value is the current unix time.
979 Returns object's date and time in the format provided by perl's
980 builtin functions C<localtime> and C<gmtime> with two exceptions:
982 1) "Year" is a four-digit year, rather than "years since 1900"

1015 =head3 Timelocal $context @time
1017 Takes argument C<$context>, which determines whether we should
1018 treat C<@time> as "user local", "system" or "UTC" time.
1020 C<@time> is array returned by L<Localtime> functions. Only first
1021 six elements are mandatory - $sec, $min, $hour, $mday, $mon and $year.
1022 You may pass $wday, $yday and $isdst, these are ignored.
1024 If you pass C<$offset> as ninth argument, it's used instead of
1025 C<$context>. It's done such way as code
1026 C<$self->Timelocal('utc', $self->Localtime('server'))> doesn't
1027 makes much sense and most probably would produce unexpected
1028 result, so the method ignore 'utc' context and uses offset
1029 returned by L<Localtime> method.

1058 =head3 Timezone $context
1060 Returns the timezone name.
1062 Takes one argument, C<$context> argument which could be C<user>, C<server> or C<utc>.
1068 Default value is C<user> that mean it returns current user's Timezone value.
1072 If context is C<server> it returns value of the C<Timezone> RT config option.
1076 If both server's and user's timezone names are undefined returns 'UTC'.
