Compare OS time to remote NTP Time Server

• Gather local time samples - OsTimeSampler 1000 3600 > local.csv
• Gather the remote time samples - NtpSampler NtpServer 1000 3600 > ntpserver.csv
• Wait for the sampling to complete (3600 seconds)
• Correlate the samples - TimeSampleCorrelation.exe local.csv ntpserver.csv 0 > raw.csv
• [Optional] Filter the data - MedianFilter 2 30 < raw.csv > filtered.csv

Compare Hyper-V Root to Hyper-V Guest

• Gather TSC offset between Root and Guest (see capture_rdtst_delta.cmd)
• Gather root time samples (launch on root) - OsTimeSampler 1000 3600 > root.csv
• Gather guest time samples (launch on guest) - OsTimeSampler 1000 3600 > guest.csv
• Correlate the samples - TimeSampleCorrelation.exe root.csv guest.csv [TscOffset] > raw.csv
• [Optional] Filter the data - MedianFilter 2 30 < raw.csv > filtered.csv
