Find the time matching in a time string using Javascript

I need to extract the time in the format "HH:MM:SS" from a string like "HH:MM:SS CEST". How can I achieve this without including any additional strings such as CEST?

Answer №1

Give this a shot:

phrase = "I have a timestamp like "07:12:45 CEST" and I am looking to extract only "23:32:16" without the time zone information or any other text attached."

var result = phrase.match("(\d{2}:\d{2}:\d{2}))

Answer №2

Topic: Time Stamp
Regular Expression: \d{2}[:]\d{2}[:]\d{2}
Validation Tool: http://regex.larsolavtorvik.com/

Answer №3

In addition to the regex methods shared earlier, an alternative approach is to utilize a date/time library such as Luxon, which offers robust parsing capabilities for handling strings. In your scenario, you can achieve this by using:

DateTime.fromFormat('12:03:40 CEST', 'HH:mm:ss')

If you only require the time component, you can extract it using the format function like so:

DateTime.fromFormat('12:03:40 CEST', 'HH:mm:ss').toFormat('HH:mm:ss')

Although this method may be slower compared to regex and necessitates the inclusion of an external library, it enables various date/time operations.

However, if your sole objective is to identify a time string within another string, regex remains a reliable choice.
