Syntax

TimeSpan.Invalid

Examples

#import "std/chrono"
using chrono

dim as TimeSpan bad = TimeSpan.Invalid( )

print bad.IsValid            '' false

'' ABSORBING: anything touching an Invalid becomes Invalid
print bad.Add( TimeSpan.FromDays( 1 ) ).IsValid         '' false
print bad.Duration( ).IsValid                            '' false

'' And it never compares equal to anything, itself included
print ( bad = TimeSpan.Invalid( ) )      '' false
