@aarush00 Please pick another issue labeled as good first issue, as this has already been picked up by another contributor.

By referring to DotNet Date Format Strings, here are the list of replacements in Java Date Format Strings

Remaining strings will be used as such from input
Shall I proceed with that conversion.

@binu-r
Please check the patterns for date and time as defined in MS SQL Server and not .net:
https://docs.microsoft.com/en-us/sql/t-sql/data-types/date-transact-sql?view=sql-server-ver15
https://docs.microsoft.com/en-us/sql/t-sql/data-types/time-transact-sql?view=sql-server-ver15

@matriv
Thanks for sharing the links. They particularly mention about how to convert strings to date or time. But we want to convert date/time to string format.

I checked DotNet format because it is mentioned in the format function specification by Microsoft.

Arguments
value
Expression of a supported data type to format. For a list of valid types, see the table in the following Remarks section.
format
nvarchar format pattern.
The format argument must contain a valid .NET Framework format string, either as a standard format string (for example, "C" or "D"), or as a pattern of custom characters for dates and numeric values (for example, "MMMM DD, yyyy (dddd)"). Composite formatting is not supported. For a full explanation of these formatting patterns, consult the .NET Framework documentation on string formatting in general, custom date and time formats, and custom number formats. A good starting point is the topic, "Formatting Types."
culture
Optional nvarchar argument specifying a culture.
If the culture argument is not provided, the language of the current session is used. This language is set either implicitly, or explicitly by using the SET LANGUAGE statement. culture accepts any culture supported by the .NET Framework as an argument; it is not limited to the languages explicitly supported by SQL Server. If the culture argument is not valid, FORMAT raises an error.

@matriv please review PR #55454
