130 ymd %Y-%m-%d
131 ymcw %Y-%m-%c-%w
132 ywd %rY-W%V-%u

134 lilian n/a
135 ldn n/a
136 julian n/a
137 jdn n/a
138 matlab n/a
139 mdn n/a
140 These designators can be used as output format string, moreover,
142 @code{lilian}/@code{ldn} and @code{julian}/@code{jdn} can also be used
143 as input format string.

166 The full documentation for strptime is maintained as a Texinfo manual.
167 If the info and strptime programs are properly installed at your site,
168 the command
169 info (dateutils)strptime
