Day and year will stay the same period of time as astrological events (1 year = 365.25 days)
Dates and time will be united to one system that can be abbreviated by any instance
Units
Units
Base unit called "chron" and equal to 1 day.
New units:
1000 years => kicen [kcn] kilochronnium
100 years => hecen [hcn] hectochronnium
10 years (decade) => decen [dcn] decachronnium
Year unit => chronnium [cn] (abbr. cen)
Month unit => hec [hc] hectochron
Week unit => dac [dac] decachron
Day unit => chron [c]
Hour unit => centichron [cc]
Minute unit => minichron [mc]
Second unit => microchron [uc]
1 minichron = 100 microchron
1 centichron = 100 minichron
1 chron = 100 centichron
1 decachron = 10 chron
1 hectochron= 10 decachron
1 chronnium = 365 chron= 3.65 hectochron = 36.5 decachron
Leap year is every 20 chronnium starting in 2020. 1 leap chronnium = 370 chron = 37 decachron

Supreme Precision
Supreme Precision
For supreme precision every 640 chronniums won't have a leap chronnium, starting at 2000.
(example: 2640, 3280, 3920 won't be a leap chronnium)
Explanation:
One year precisely 365.2421904 days
Julian calendar made it 365.25 days
Gregorian calendar improved it to 365.2425 days a year, which makes an error: 1 day in 3230 years
In UDATE system is 365.2421875 days a year, which makes an error of 1 day in 345600 years (which will make an error of 36 years in the age of the earth 4.5 billion years)

Days in the year: 365.2421904
Gregorian: (365.25*400 - 3)/400 = 365.2425 days/year
error: 1/(365.2425-365.2421904) = 1 day a 3229.9 years
UDATE: (365.25*640 - 5)/640 = 365.2421875 days/year
error: 1/(365.2421904-365.2421875) = 1 day a 345600 years
As the earth rotating slower and slower, UDATE system will be more and more precise, Gregorian system will be les and less precise.
