== Software ==
Included BASIC and CP/M+ drivers:
* RSX.BAS (loader) and RSX.BIN (binary)- allows to change the time under BASIC, using following RSX commands** |SETTIME,yy%,mm%,dd%,dayofweek%,hour%,min%,sec%** |ASKTIME,@yy%,@mm%,@dd%,@dayofweek%,@hour%,@min%,@sec%** |POKERTC,index%,value%** |PEEKRTC,index%,@value%** |TIMEON,xpos%,ypos%,interval%** |TIMEOFF** |ALARMON,hour%,min%,sec%,flag%** |ALARMOFF* CLOCK.COM - installs the clock under CP/M+ (thereafter** Thereafter, it should be accessible with standard DATE command, and, it should add timestamps to files).** According to english manual, time is set by "CLOCK dd/mm/yy hh/mm/ss" rather than by using the DATE command (?)** Unknown how the timestamps are stored on disk? The normal AMSDOS filesystem / directory entries don't include timestamps.** According german manual, something is (the startup message?) "Datomat RTC und Cdos sind Warenzeichen von CMS International" (=Datomat RTC and Cdos are trademarks of CMS International)
== Timestamps ==
This entry contains the time stamps for the extents using the previous three directory entries. Note that you really have time stamps for each extent, no matter if it is the first extent of a file or not. The structure of time stamp entries is:
1 byte minute in BCD format
