The customer created lotusscript and it uses Today function as below.
In HCL Nomad environment (iPad use), when the script ran, it showed the date as "yy/mm/dd", not "yyyy/mm/dd".
For example, Nomad showed the date as "19/10/1", not "2019/10/01".
To show four-digit year, it is necessary to use Format function as below.
Msgbox Format(Today, "yyyy/mm/dd")
They found that Now function also shows two-digit year.
