If the week containing January +1 has four or more days in the new year, then it is week 1; otherwise +it is week 53 of the previous year, and the next week is week 1. +.TP +%W +is replaced by the week number of the year (Monday as the first day of +the week) as a decimal number (00\*(en53). +.TP +%w +is replaced by the weekday (Sunday as the first day of the week) +as a decimal number (0\*(en6). +.TP +%X +is replaced by the locale's appropriate time representation. +.TP +%x +is replaced by the locale's appropriate date representation. +.TP +%Y +is replaced by the year with century as a decimal number. +.TP +%y +is replaced by the year without century as a decimal number (00\*(en99). +.TP +%Z +is replaced by the time zone name, +or by the empty string if this is not determinable. +.TP +%z +is replaced by the offset from the Prime Meridian +in the format +HHMM or \*-HHMM as appropriate, +with positive values representing locations east of Greenwich, +or by the empty string if this is not determinable. +The numeric time zone \*-0000 is used when the time is Universal Time +but local time is indeterminate; by convention this is used for +locations while uninhabited, and corresponds to a zero offset when the +time zone abbreviation begins with +.q "\*-" . +.TP +%% +is replaced by a single %. +.TP +%+ +is replaced by the date and time in date(1) format. +.SH SEE ALSO +date(1), +getenv(3), +newctime(3), +newtzset(3), +time(2), +tzfile(5) |
