Follow up to #53981. Fixes an issue introduced with negative years and fixed-with date formats: ```julia julia> Dates.DateTime("-20240521", "yyyymmdd") ERROR: ArgumentError: Month: 40 out of range (1:12) Stacktrace: [1] DateTime(y::Int64, m::Int64, d::Int64, h::Int64, mi::Int64, s::Int64, ms::Int64, ampm::Dates.AMPM) @ Dates ~/Development/Julia/aarch64/latest/usr/share/julia/stdlib/v1.12/Dates/src/types.jl:246 [2] parse(::Type{DateTime}, str::String, df::DateFormat{:yyyymmdd, Tuple{Dates.DatePart{'y'}, Dates.DatePart{'m'}, Dates.DatePart{'d'}}}) @ Dates ~/Development/Julia/aarch64/latest/usr/share/julia/stdlib/v1.12/Dates/src/parse.jl:294 [3] DateTime(dt::String, format::String; locale::Dates.DateLocale) @ Dates ~/Development/Julia/aarch64/latest/usr/share/julia/stdlib/v1.12/Dates/src/io.jl:555 [4] DateTime(dt::String, format::String) @ Dates ~/Development/Julia/aarch64/latest/usr/share/julia/stdlib/v1.12/Dates/src/io.jl:554 [5] top-level scope @ REPL[4]:1 ``` This PR makes it so that fixed-width formats require the specified number of digits. I also decided to only add the sign parsing for years to running into performance issues with parsing sign information where it isn't expected.

Fixes JuliaLang#50328. Originally checked on version 1.10.0 but still relevant in the current version in master Bug: In method Date(str), when given a negative year as an argument (ex: "-2000"), it would output an error while in Date(int) once given a negative year (ex: "-2000") it would work as intended returning "-2000-01-01". Fix: In function tryparsenext_base10 the character '-' wasn't being accounted so i check if it existed in the first iteration of the string and if yes I would multiply the output * -1. Test: Added some tests that verify this specific Fix. --------- Co-authored-by: Jameson Nash <vtjnash@gmail.com> Co-authored-by: Viral B. Shah <ViralBShah@users.noreply.github.com>
