Adjust Time Shift based on Travel Log

`TAdjust()` is a function that corrects data points and time-shift based on travelling log. Note that it is important to ensure that the UTC-offset value is correct. When in doubt, please use the UTC function or consult IANA table in the package. Daylight saving will not be reassessed as in BriefSum function.

Usage

TAdjust(Bdf, TLog, TZ = NULL, fork = FALSE)

Arguments

Bdf

A BriefSum object containing per-day metadata for the recording.

TLog

A structured travel log containing date of travel and local time zone. Use `TravelLog()` to generate template.

TZ

The time zone when the recording started. (default = "NULL", which will disregard the use of the initial geographical location-based time zone indicator)

fork

Logical, if TRUE, it will use parallel processing to speed up the computation. Default is FALSE.

Value

A BriefSum object with adjusted data points and time shift based on travel log.

Examples

if (FALSE) { # \dontrun{

# Import sample data
data (FlyEast)

# Create quick summary of the recording with adjustment for daylight saving.
BdfList <- BriefSum (
    df = FlyEast,
    SR = 1 / 60,
    Start = "2017-10-19 13:45:00"
)

# Extract only the summary report
Bdf <- BdfList$Bdf

# Import sample travel Log
data (TLog)

# Adjust time shift based on travel log
Bdf.adj <- TAdjust (Bdf, TLog)

# Display the summary
View (Bdf)
View (Bdf.adj) ### Focus on the dates after 2017-11-01
