Description

Add time (in seconds since tagon or datetimes in UTC and/or local timezone) to a tibble or data-frame with event times (conversion between datetime and seconds_since_tagon formats)

Usage

add_event_times(x, start_x, tagon_time)

Arguments

x	input data frame: vector, tibble, or data frame. There should be one column that gives either seconds_since_tagon or UTC time already present.
start_x	name of the variable in x that gives the times
tagon_time	string giving the tag recording start time (or the info sensor data structure). Can be found in tag_dataset$info$dephist_device_datetime_start. Format: day month year hours minutes seconds.

Value
