Actually I have already installed RTC (NXP PCF2129) and SPI Kanji ROM, but I have forgotten to make command to utilize them in TinyBasicPlus. This time I implemented date related functions.

Simply date and time command will return current ones,

>date
15, 18, 10
>time
18:10:21

but even the screen got bigger, these character are a bit hard to read, so this time

btime and bdate are added (both will show you larger graphic characters).

Maybe some of you ( if you are agree, I don't think you are major in hackaday..), I implement

jdate

command which provides you "date and time in Japanese expression". Actual operation can be found in the following movie, and its source is uploaded to github... I hope you will have fun.
