isRecentlyModified

public static boolean isRecentlyModified(String lastModifiedTime,
                                         Instant expectedLMTUpdateTime)

Tries to identify if an operation was recently executed based on the LMT of a file or folder. LMT needs to be more recent that the original request start time. To include any clock skew with server, LMT within DEFAULT_CLOCK_SKEW_WITH_SERVER_IN_MS from the request start time is going to be considered to qualify for recent operation.

Parameters:

lastModifiedTime - File/Folder LMT

expectedLMTUpdateTime - original request timestamp which should have updated the LMT on target

Returns:

true if the LMT is within timespan for recent operation, else false
