示例 1：

Python3

# R program to illustrate
# strptime function
 
# Specifying a time
x <- "13:15:17"

示例 2：

Python3

# R program to illustrate
# strptime function
 
# Specifying a date and time
x <- "10-02-2020 05:05:06 AM"
 
# Calling strptime() function
# over specified date and time, template
# and time zone
y <- strptime(x, "% d-% m-% Y % I:% M:% S", "GMT")
 
# Getting parsed date and time
y

输出：
