Arguments

n

Number dates to draw. Default: n = 1.

from

Earliest date (as string). Default: from = "1970-01-01 00:00:00".

to

Latest date (as string). Default: to = Sys.time().

Examples

# NOT RUN {
# Basics:
sample_time()
sample_time(n = 10)

# Specific ranges:
sort(sample_time(n = 10, from = (Sys.time() - 60)))  # within the last minute
sort(sample_time(n = 10, from = (Sys.time() - 1 * 60 * 60)))  # within the last hour
sort(sample_time(n = 10, from = Sys.time(), 
                           to = (Sys.time() + 1 * 60 * 60)))  # within the next hour
sort(sample_time(n = 10, from = "2020-01-01 00:00:00 CET", 
                           to = "2020-01-01 00:00:01 CET"))  # within 1 sec range
 
# Note: Oddity with sample(): 
sort(sample_time(n = 10, from = "2020-01-01 00:00:00 CET", 
                           to = "2020-01-01 00:00:00 CET"))  # range of 0!
# see sample(9:9, size = 10, replace = TRUE)
