DIZtools (version 1.0.3)

time_diff_print: Calculate time difference of two timestamps, round the value and return a string with suiting unit.

Description

Create string with time difference in suitable unit. Additional automatically add the remaining time depending on the position in an iteration process, or the estimated time of arrival by just providing the current and total iteration step(s). A more fancy option might be the package progressr. See progressr for a corresponding code snippet.

Usage

time_diff_print(
  older_timestamp,
  newer_timestamp = NULL,
  iteration = NULL,
  iterations = NULL,
  remaining_time = TRUE,
  eta = TRUE,
  prefix_iteration = "Iteration ",
  prefix_time_elapsed = "Time elapsed: ",
  prefix_time_remaining = "Remaining: ",
  prefix_eta = "ETA: ",
  digits = 2,
  thousands_separator = "",
  decimal_separator = "."
)

Value

A list with one element per row of the input file

Arguments

older_timestamp

(POSIXct) Start time.

newer_timestamp

(POSIXct, Optional) End time. If not set, the current time will be used.

iteration

(Numeric, Optional) The current iteration if also the time process within all iterations additional to the elapsed time is of interest.

iterations

(Numeric, Optional) The total number of iterations.

remaining_time

(Boolean, Optional, Default = TRUE) Should the estimated time needed to finish all iterations be displayed?

eta

(Boolean, Optional, Default = TRUE) Should the estimated time of arrival needed to finish all iterations be displayed?

prefix_iteration, prefix_time_elapsed, prefix_time_remaining, prefix_eta

Prefixes for the output string.

digits

(int, optional) The number of digits after the decimal separator to round to.

thousands_separator

(string, optional) Used as mark between every 3 decimals before the decimal point.

decimal_separator

(string, optional) The character to be used to indicate the numeric decimal point.

Examples

## Since no second timestamp is provided, the current time
## (currently 2023-03-08) will be assumed:
DIZtools::time_diff_print("2023-01-01 10:00")
#> [1] "Time elapsed: 66.20 days"
DIZtools::time_diff_print("2023-01-01 10:00", iteration = 7, iterations = 10)
#> [1] "Iteration 7 of 10 (70.00 %), Time elapsed: 66.20 days
#>     (Remaining: ~ 28.37 days, ETA: ~ 05. Apr 2023 - 23:42 UTC)"
