Formats the date-time with a pattern into a variable; returns false if the pattern is bad.
DateTime.TryFormat( pattern, result )
#import "std/chrono"
using chrono
dim as DateTime d = DateTime( 2026, 8, 13, 14, 30, 5, 123 )
dim as ustring out_
'' The non-raising form of the pattern ToString: FALSE on a pattern it
'' cannot render, rather than an Invalid-looking string
if d.TryFormat( "yyyy-MM-dd HH:mm", out_ ) then print out_
print d.TryFormat( "yyyy", out_ ) '' true
print out_ '' 2026
