Modern Chrono TimeSpan IsValid

Home › Date and Time (Chrono) › Chrono Date and Time › TimeSpan.IsValid

TimeSpan.IsValid

Returns true unless the duration overflowed or came from bad input.

Syntax

TimeSpan.IsValid

Examples

#import "std/chrono"
using chrono

print TimeSpan.FromDays( 1 ).IsValid      '' true
print TimeSpan.Invalid( ).IsValid         '' false

'' Overflow and NaN both land here rather than raising
print TimeSpan.FromDays( 1e300 ).IsValid  '' false

'' The ONLY correct test -- comparison with an Invalid is always false
