Modern Chrono Stopwatch GetTimestamp

Home › Date and Time (Chrono) › Chrono Date and Time › GetTimestamp

GetTimestamp

Returns the raw monotonic counter; divide a difference by Frequency to get seconds.

Syntax

Stopwatch.GetTimestamp( ) as int64

Notes

• Platform units, not 100 ns ticks: divide a difference by Frequency( ) to get seconds.
• It is the primitive a Stopwatch is built on, exposed for code that wants to time something without holding one.
• Monotonic, so it never goes backwards across an NTP correction or a DST change -- which TIMER does not promise.

Examples

#import "std/chrono"
using chrono

dim as int64 a = Stopwatch.GetTimestamp( )
sleep 20, 1
dim as int64 b = Stopwatch.GetTimestamp( )

print b > a                  '' -1 (true) -- monotonic

'' PLATFORM UNITS: divide by Frequency to get seconds
print ( b - a ) / Stopwatch.Frequency( ) < 1.0                '' -1 (true)
