Check if a date field has date or timestamp or date×tamp
Hi,
In a field, I should receive the date with time stamp in a particular field. But sometimes the vendor sends just the date or the timestamp or correctl the date×tamp. I have to figure out the the data is a date or time stamp or date×tamp.
If it is date then append "<space>00:00:00" to it.
If it is a time stamp, store the data in a different file(invalid_dttmstmp.txt) and remove from this file.
If it is a date timestamp then do nothing.
Input file:
Code:
File1
====
Field 1
=====
00:00:00
<space>01:01:01
2012-02-25 00:30:14
2012-02-25
Expected output
Code:
File1
====
Field 1
=====
2012-02-25 00:30:14
2012-02-25 00:00:00
invalid_dttmstmp.txt
===============
Field 1
======
00:00:00
<space>01:01:01
I coded for date part and that works. I need help with time stamp validation
Thanks

Is it correct to use
Code:
touch -c -d 20120225 dummy --> to check the date
touch -c -t 201220252359.59 -->to check date×tamp
Is this logic correct. Also can this handle around 4000 different values (if I go for loop) with in a few minutes (1-2min)??
Could someone tell me how to get the date/time (to the second) a file was last modified? I need to know if a file was modified in the last 30 seconds from the system date. I'm on AIX/unix 4.3 (3 Replies)

http_cache_last_modified
HTTP_CACHE_LAST_MODIFIED(3) 1 HTTP_CACHE_LAST_MODIFIED(3)http_cache_last_modified - Caching by last modificationSYNOPSIS
bool http_cache_last_modified ([int $timestamp_or_expires])
DESCRIPTION
Attempts to cache the sent entity by its last modification date.
If the supplied argument is greater than 0, it is handled as timestamp and will be sent as date of last modification. If it is 0 or omit-
ted, the current time will be sent as Last-Modified date. If it's negative, it is handled as expiration time in seconds, which means that
if the requested last modification date is not between the calculated timespan, the Last-Modified header is updated and the actual body
will be sent.
A log entry will be written to the cache log if the INI settinghttp.log.cache is set and the cache attempt was successful.
Note
This function may be used in conjunction with http_send_data(3), http_send_file(3) and http_send_stream(3).
PARAMETERS
o $timestamp_or_expires
- Unix timestamp
RETURN VALUES
Returns FALSE or exits on success with 304 Not Modified if the entity is cached. See the INI settinghttp.force_exit for what "exits"
means.
EXAMPLES
Example #1
A http_cache_last_modified(3) example
Caching for 5 seconds.
<?php
http_cache_last_modified(-5);
printf("%s
", http_date());
?>
