adb shell date帮助

adb shell date --help
usage: date [-u] [-r FILE] [-d DATE] [+DISPLAY_FORMAT] [-D SET_FORMAT] [SET]

Set/get the current date/time. With no SET shows the current date.

-d      Show DATE instead of current time (convert date format)
-D      +FORMAT for SET or -d (instead of MMDDhhmm[[CC]YY][.ss])
-r      Use modification time of FILE instead of current date
-u      Use UTC instead of current timezone

Supported input formats:

MMDDhhmm[[CC]YY][.ss]     POSIX
@UNIXTIME[.FRACTION]      seconds since midnight 1970-01-01
YYYY-MM-DD [hh:mm[:ss]]   ISO 8601
hh:mm[:ss]                24-hour time today

All input formats can be preceded by TZ="id" to set the input time zone
separately from the output time zone. Otherwise $TZ sets both.

+FORMAT specifies display format string using strftime(3) syntax:

%% literal %             %n newline              %t tab
%S seconds (00-60)       %M minute (00-59)       %m month (01-12)

%x locale date    %X locale time    %c locale date/time
